Introduction
In this week’s Afterschool Adventure, children will use number powers to solve problems and
save the day! They will use grouping power to save a parade, skip counting power to catch a
pie-snatching thief, and speed counting and place value power to pay a royal ransom and bring
a missing king and queen back home. On the last day, children will use zero power to foil some
pranksters who are out to ruin a party. Each section of this weeklong adventure is introduced
by a video clip or online game that encourages children to explore math concepts and skills
related to grouping and place value.

Part 1: Parade Float Fix-Up (20 minutes)
PLAY
Cyberchase: Parade Day
Put the finishing touches on Buzz and Delete’s parade float by using a special crane to place different
groupings of bulbs into the empty sockets.
Gather children at your computer or interactive whiteboard so everyone can see.
Leader: Welcome to the Number Power Afterschool Adventure! This week, with a little help from our PBS KIDS friends, we are going
to use number powers to solve problems and save the day. Today, we’re going to use the power of grouping to help Buzz and
Delete from Cyberchase get ready for a parade.
Ask the children what they think grouping means and correct or confirm their ideas.
Leader: That’s right! Grouping is when you break a large collection into smaller groups. Grouping can give you the power to organize
and plan. Let’s see how!
Choose twelve children to stand up in front of the group (six also works if you don’t have 12 children in your program, just be sure to
use half of the numbers below when following leader directions).
Leader: Buzz and Delete are getting ready for a parade. Imagine that you are in a marching band in a parade and you need to march
in lines, with six children in each line. Show me how you could organize yourself into groups of six.
Pause to allow children to complete the task.
Leader: You’ve organized yourselves into two equal groups of six. Now, what if you had to march in lines of three?
How would you group yourselves?
Have children group themselves into equal groups of three. Then challenge them further, asking them to groups themselves into lines
of four and two.
Leader: Now you can see that depending on what you want to do, being able to organize things into groups is very important!
Let’s see how else we can use our grouping power to get ready for Buzz and Delete’s parade.
Access the game and listen to the introduction. Then reinforce the object of the game for the children.
Leader: The citizens of Botopolis are throwing a parade for Buzz and Delete. They started building a parade float, but they need
help finishing it. Look at the holes to see how many light bulbs you need to fill. You can choose how many holes to fill at one
time by clicking on the numbers at the top of the screen. Try to fill in the bulbs in the fewest number of moves.
Demonstrate how to fill in the empty sockets in the first scenario using the robot claw. Then, call on children to come up individually
to fill in the sockets in the next two scenarios. Include the rest of the group by asking:
• What do you think of your classmate’s strategy for filling in the missing light bulbs?
• How else can we fill in the missing light bulbs?
• Is there a way to fill in the light bulbs using fewer moves?

Cyberchase: Ping Pong Pickup
The floor is covered with ping pong balls, and Buzz and Delete need help putting them in boxes.
Encourage children to strategize about how many ping pong balls to pick up in each move,
and have them predict how many moves they will need to make in total.
EXPLORE
Grouping
If you would like to give children additional practice with grouping, provide them with pennies, paperclips, Unifix cubes,
or other manipulatives, and challenge them to organize the manipulatives into groups of three, four, or five.

Part 2: Pie Thief Capture (20 minutes)
WATCH
Odd Squad: Missing Pies (1:21)
Miss O and O’Donahue investigate the theft of some pies from the bakery. But before they can
figure out who stole them, they need to count how many are missing. As they count the pies,
they demonstrate how to count by fives.
Gather children at your computer or interactive whiteboard so everyone can see.
Leader: Welcome back to the Number Power Afterschool Adventure! This week, we’re using number powers to solve problems and save
the day. Yesterday, we saved Buzz and Delete’s parade by using our grouping powers to fill in the missing lights in the parade
float. Today, we’re going to use our skipcounting powers to help the Odd Squad agents save the city from a pie thief.
Access the video and introduce it to the children.
Leader: There’s a thief on the loose, and he’s stolen some pies from the bakery! In order to find out who did it, Odd Squad agents have
to find out how many pies were stolen in the first place. They know that when counting objects, it’s easier to form groups,
and then skip count. Let’s watch this video to see how they do it.
Press play and watch the video with your children. Afterwards, ask:
•
How did the Odd Squad team use groups to help them count? (They counted the pies in groups of five.)
•
How many pies were in each row, or group? (5)
•
How many pies were there in total? (22)
•
How did skip counting (counting in groups) make it easier for the Odd Squad to count up all the missing pies?
(They didn’t have to count one by one.)
•
Who do the agents think stole the pies? (Tommy Twosie)
Leader: The agents think Tommy Twosie stole the pies since he loves the number “2” and 22 pies were missing. Now they’re wondering
if Tommy Twosie could have stolen other pies that have gone missing at different bakeries around town! I’m going to give you
a handout that shows pies stolen from other bakeries in town. Count them up in groups, and figure out how many were stolen
from each bakery. If the answer is 22, that means Tommy Twosie did it!
EXPLORE
Give each child a copy of the Pie Thief handout. Encourage them to work in pairs or small groups to
skip count the pies in rows, as they are arranged on the handout. If any of the total pies missing adds up
to 22, have children circle those pies – those are the ones stolen by Tommy Twosie!
When children are finished, have them return together as a large group to share their answers. Ask:
•
How many pies did you count in all? (From left to right: 22, 26, 24, and 22.)
•
How many pies were in each row? (From left to right: 3, 4, 2, and 10)
•
Which arrangement did you think was easiest to count?
•
Which pies were stolen by Tommy Twosie? (The first group and the last group.)

Leader: You’ve seen how counting lots of objects—in this case, pies—can be easier if you form groups and skip count. And by counting
the number of pies missing, you helped the Odd Squad agents on their mission to track down the pie thief. Congratulations on
mastering another number power!

Cyberchase: Using Grouping to Count Quickly (3:53)
The Fairy Tale King has been kidnapped, and the townspeople need 777 golden eggs to pay his ransom
and ensure his safe return. The Cybersquad comes up with a quick and efficient way to keep track of
the eggs without counting them one by one.
Gather children at your computer or interactive whiteboard so everyone can see.
Leader: Welcome back to the Number Power Afterschool Adventure! This week, we’re using number powers to solve problems and
save the day. So far, we’ve helped Buzz and Delete save a parade, and we helped the Odd Squad track down a pie thief using
our skip counting powers. Today, we’ll count out ransom for a king using speed counting powers!
Access the video and introduce the story.
Leader: In this video clip from Cyberchase, Jackie, Matt, and Inez are visiting the Fairy Tale Kingdom. The king has been kidnapped,
and the townspeople need to trade 777 golden eggs to get him back—or else he’ll live miserably ever after. But a wicked
queen has cast a spell, taking away everyone’s ability to count.
Press play and watch with the children. Pause at :35 and ask:
•
What is the problem?
(The townspeople need to count lots of eggs. They can’t remember how to count very well and don’t have much time.)
•
How are Jackie, Matt, and Inez counting the eggs now? (One at a time.)
•
How would you solve the problem?
Continue playing the video, and pause again at 1:45. Ask:
•
What do you think Inez meant when she said, “group and conquer”?
•
How will placing the eggs in groups of ten help the CyberSquad solve their problem?
(Organizing the eggs into groups of ten will help them count more quickly.)
Continue playing, and pause one last time at 2:28. Explain Jackie’s reasoning: If they stack ten boxes of ten eggs, they will have
100 eggs in each stack. Point to each box in the stack, counting by tens to reach 100.
Once the video clip ends, choose another three-digit number and have children work together to count units equaling the number.
Use base ten blocks if available, otherwise you may use craft sticks. (Bundles of craft sticks (10) work for tens, and stacks (100) of them
work for hundreds.) Use a stopwatch or your wall clock to time children counting to the number you have chosen using both methods
illustrated in the video—counting one by one and counting using the groups of ten and one hundred—to confirm which way is faster.
Leader: Today, you’ve seen how organizing objects into groups can help you gain speed counting power. This power helped the
townspeople in the Fairy Tale Kingdom quickly organize golden eggs for the king’s ransom. Next time we meet,
we’ll see if the townspeople can gather 777 eggs and bring the king back home.

Otto and Oscar have captured a bunch of furry, frantic centigurps that got loose—but exactly
how many do they have? Corralling them in groups of ten, they discover that they have collected
50... which means 50 more are still on the loose! Watch the video with children, and then have them
count out 50 “centigurps” (pom poms) on their own, by organizing them into five groups of ten.

WATCH
Cyberchase: Ones, Tens, and Hundreds (2:14)
The Cybersquad has organized a collection of eggs into hundreds, tens, and ones. As they count the eggs,
they demonstrate place value.
Gather children at your computer or interactive whiteboard so everyone can see.
Leader: Welcome back to the Number Power Afterschool Adventure! This week, we’re using our number powers to solve problems and
save the day. Yesterday, we practiced our speed counting powers. Today, we’re going to use place value power to count out
the right number of eggs to save the Fairy Tale King.
Access the video and watch with your children. Pause at :26 and write the number 779 on your chalkboard or whiteboard. Ask:
•
What does the number 7 mean here? Point to the hundreds place. (There are (7) hundreds.)
•
What does the number 7 mean here? Point to the tens place. (There are (7 ) tens.)
•
What does the number 9 mean here? Point to the ones place. (There are (9) ones.)
If children need help making the connection, show them the Golden Egg so they can see a more concrete
illustration of place value. Then ask:
•
What does the Cybersquad need to do to have 777 eggs? (Take two away.)
Watch the rest of the video with your children.
Leader: The Cybersquad ended up with 777 eggs, and can now exchange them for the safe return of the Fairy Tale King.
We saw in the video how the same number can mean something different depending on where it is – for example,
the ones place, the tens place, or the hundreds place. That’s called place value. Let’s explore place value some more.
Share the following story problem with children.
The Fairy Tale queen has been kidnapped! The townspeople need to come up with a certain number of eggs to ensure her safe return.
Let’s figure out how many eggs they need to collect using these clues:
•
The number of eggs needed for the queen’s ransom is MORE than the number of eggs needed for the king’s ransom.
•
There is a five (5) in the number, but it’s not in the tens place.
•
There is also a six (6) and a nine (9) in the number.

Start with the first clue. Ask: Where does the five go?
Help children realize that the 5 can’t go in the tens place because the clue says it can’t go there. And the five (5) can’t go in
the hundreds place because that would mean the queen’s ransom was less than the king’s (since five (5) hundreds is less than
seven (7) hundreds). The five (5) must go in the one’s place. Fill it in like this:
King’s ransom
Queen’s ransom
Hundreds

Now ask: Where does the six belong?
Help the children understand that the six can’t go in the hundreds place, because that would mean the queen’s ransom was

The Electric Company: Revenge of the Zeros
Danny and Annie try to ruin Paul’s banana festival party at the Electric Diner by scrambling Hector’s
list of party supplies, causing Marcus to order ten one-man banana bands instead of one.
Gather children at your computer or interactive whiteboard so everyone can see.
Leader: Welcome back to the Number Power Afterschool Adventure! This week, we’re using number powers to solve problems and save
the day. Yesterday, we saved the king and queen of Fairy Tale Kingdom by learning about place value and counting out eggs
for their ransom. Today, we’re going to use the power of zero to save a banana festival party.
Access the video and scroll down to find The Electric Company: Revenge of the Zeros-Part 2 (3:55).
Introduce the video to the children before watching.
Leader: In this video clip, the Electric Company is helping Paul the Gorilla throw a banana festival party. But the Pranksters,
Danny and Annie, are trying to ruin the party! They’re ruining it by adding and subtracting zeros to the list of party supplies.
Let’s learn about the power of zero and watch as the Pranksters change the amount of shiny banana balloons from 10 to 0.
Press play and watch the video with your children.
Leader: The Pranksters aren’t done yet! Now they’re going to change the numbers again for the other party supplies.
Use the down arrow to scroll to The Electric Company: Revenge of the Zeros-Part 3 (5:22) and watch it with the children. Afterwards,
discuss what you saw. Ask:
•
How many one-man banana bands did the Electric Company want at their party? (1)
•
When the Pranksters added a zero to the number, how did the amount change? (It became a 10.)
Write a 1 on your chalkboard or whiteboard and then add a zero. Ask:
•
How does adding a zero to this number change the value of the 1? (Instead of 1 ones, it now has a value of one (1) ten.)
Leader: Adding a zero changed the value of the one, and it changed the whole number from a one to a ten. That’s the power of zero!
Let’s see if you can use the power of zero to fix the whole list of party supplies and save the banana festival party!
Hand out the Banana Festival Party Supplies and ask children to correct Barry the Banana Man’s list
of items to match Hector’s banana festival supply list. Children will need to change the amounts by adding
or taking away a zero and match the list as you read it aloud.
Leader: I’m going to say out loud all the items that the Electric Company needs for the banana festival
party, and how much they cost. I want you to correct the list from the Barry the Banana Man.
His list was scrambled by the Pranksters and all the zeros are in the wrong places! I’ll read aloud
how many items are needed for the party, and you will make both lists match by adding or
crossing out zeros.
