Number Line Math
Activity Chart
Designed to meet these objectives:
Math
• Students will understand mathematical operations using whole, positive integers.
• Students will perform mental math.
• Students will demonstrate algebraic thinking.
Large enough for the entire class to view at once, your new interactive number line enables
children to see early math concepts in action! With the help of six cute counting frogs,
students learn to solve over 100 addition, subtraction, greater than/less than, and number
sequencing problems—hands on!
What’s Included
•
•
•
•
18" x 533⁄4" magnetic pocket chart
60 blue number cards (1–100)
6 counting frogs
Hook & loop dots
• 31 activity cards (20 double-sided)
• 20 yellow number cards (1–20)
• 2 storage pocket cards
Before You Begin
The Number and Activity Cards
You will find a packet in this kit that contains the activity, number, and storage pocket cards.
Before you set up the chart, you will need to cut these cards along the dashed lines. At the
bottom of the chart, you will find a storage pocket divided into two sections. Place the
Number Cards header in the left pocket and the Activity Cards header in the right pocket,
and store the number and activity cards accordingly.
Note: Be sure to use only dry-erase markers on the write & wipe cards. To prevent ink from
beading, prime the cards by drawing on them with a dry-erase marker, and then erase by
rubbing vigorously with a dry textured cloth or paper towel. Repeat if necessary. Remember
to wipe away any markings left on the cards before putting them away. Do not allow
markings to remain overnight.

The Counting Frogs
Cut the counting frogs along the dashed lines and attach a rough hook & loop dot to the
back of each one. Place the frogs on the two hook & loop strips located above the number
line (three frogs per strip).
The Number Line
Place a fuzzy hook & loop dot in the center of each of the 20
number line markers as shown. (Frogs will be attached to these
dots while students are solving equations.)
Once the cards are cut and prepared, the frogs are in place, and the hook & loop dots are
attached to the chart, you’re ready to display the pocket chart. It’s magnetic, so it sticks to
surfaces such as metallic white boards. You can also hang it on a pocket chart stand or
display it on a bulletin board. Choose a place where students can easily see and reach the
chart. Then, try the activities below!
Addition and Subtraction
Addition
• Build a 1–20 number line using the blue number cards.
• To create an addition problem, simply place any of the Start at-, Move forward-, and
Where did you land? activity cards in the pocket chart as shown. (The activity cards that
represent 2 + 4 = 6 are shown below.)
• Read the activity cards aloud and invite a volunteer to help you work through the addition
problem using the counting frogs.
• When your volunteer has “hopped” forward four spaces on the number line, ask her
where she’s landed. (The answer should be six.) Now invite her to place the yellow 6 card
in the pocket as shown. After you complete each addition activity, discuss the problem so
students understand that when they move forward on a number line, they are doing two
things: counting forward and adding.
2
Subtraction
To build and practice subtraction problems, follow the same process as for addition—but this
time, use the Start at-, Move back-, and Where did you land? cards.
Be sure to discuss each completed problem. Help students understand that when they move
backward on a number line, they are doing two things: counting backward and subtracting.
Note: The addition and subtraction activity cards are designed to be used with a 1–20 number
line. The sequencing and greater than/less than activity cards work with any number line
combination up to 100!
Sequencing
• Build a number line that includes only the numbers on which you want your students to
focus.
• To create a sequencing problem, simply display one of the following activity cards:
Which number comes between ____ and ____?
Which numbers come between ____ and ____?
Which number comes before ____?
Which number comes after ____?
• Fill in the blank(s) on the activity card you’ve chosen and place it in the chart. (The Which
numbers come between ____ and ____ ? card is used below to demonstrate a sequencing
activity in which the blanks have been filled in with the numbers 85 and 89.)
• Call on a student and ask him which numbers come between 85 and 89. To help the
student get started, instruct him to place two frogs on the number line: one above the 85
card and another one above the 89 card.
• Ask the student to identify the numbers between the two frogs. Each time he calls out a
number, have him place a frog above that number.
Note: You can also create number lines that allow students to count by twos, fives, and tens!
3
Greater Than/Less Than
• Build a number line that incorporates the numbers on which you want students to focus.
• Ask your students what they notice about the numbers on the number line as they count
from left to right. Help them to understand that the numbers get bigger.
• Choose an activity card to display, fill in the blank(s), and place it in the chart. Remember,
if you don’t want to write on the cards, you can say the numbers aloud when you read
them. (The Which number is greater: ____ or ____ ? activity card is used below to
demonstrate a greater than/less than activity in which the blanks have been filled in with
the numbers 25 and 26.)
• Read the question on the activity card aloud. Ask a volunteer to place a frog on the number
line above the 25 card. Now ask her to place a frog on the number line above the 26 card.
(If a student isn’t sure which number is greater, remind her that as you move forward on the
number line, the numbers get bigger.)
Meeting Individual Needs
ELL
• Before working with the number line, review key words such as “forward,” “between,”
and “greater.” Encourage students to write the words in their math journals and have
them add illustrations or diagrams to help them remember the meaning of each word.
Reteach/Extra Support
• Gather a small group of students and pre-teach the concept before introducing it with
the whole class. Use fewer numbers on the number line or focus on lower numbers.
• Invite students to work with partners. Have one child read the activity cards while the
other child moves the frog. Then, have the partners switch roles.
Challenge
• Encourage students to draw their own number lines, extending the numbers above 20.
Prompt them to write addition, subtraction, sequencing, and comparison problems on
index cards. Then, have students exchange problems with other students and use their
number lines to solve them.
