Let your student use her own base 10 blocks to represent 3 hundreds, 3 tens,
and 6 ones. Instruct her to trace the numbers below each model and then write
the number of hundreds, tens, and ones in the modified place value chart.
Finally, say together the number, 336.

Counting and Reading Numbers to 1,000
Guided Practice: Activity Sheet 19
Name
•Tell your student that on this page he will review counting and reading numbers
to 400 by finding a mystery number. Each clue will help him to eliminate a
number balloon until only one balloon is left—the mystery number. Read
together each clue in the list in order, starting with clue A. Since the number is
not less than 50, ask your student which number is less than 50. Elicit that since
13 is less than 50, it cannot be the mystery number. Tell your child to mark an X
on (or to color) the number 13 balloon. Read together the next clue in the list,
clue B. Ask, “Since the mystery number is not more than 400, which number is
more than 400?” Elicit that 401 is more than 400, so instruct your child to mark
an X on (or to color) that balloon.

he has been writing the numbers 101 to 110, so this place value chart needs to

Using Repeated Addition with TouchPoints
Guided Practice: Activity Sheet 55
[ Skip counting is introduced here, although your child may still use TouchPoints to count on to find
the totals.]
•Before starting the page, draw a number line from 0 to 15 on the board to help
your child skip count by threes. Draw larger tic marks for the numbers 3, 6, 9,
12, and 15. Point to 0, and say, “Let’s skip count by threes to find 3 + 3.” Draw
arrows from 0 to 3 and from 3 to 6. Then say together, “3 plus 3 equals 6.” Say,
“2 groups of 3 equals 6.” Now show how to find 3 + 3 + 3. Again, start at 0, draw
arrows from 0 to 3, from 3 to 6, and from 6 to 9. Ask, “How many jumps did we
make?” Elicit that 3 jumps were made—this shows 3 groups of 3. Write 3 x 3 and
3 + 3 + 3 on the board, and say, “3 groups of 3 is the same as 3 x 3 or 3 + 3 + 3.”
•Continue using the number line in the same manner to skip count to find
3 + 3 + 3 + 3 = 12 (4 groups of 3) and 3 + 3 + 3 + 3 + 3 = 15 (5 groups of 3).
•Now direct your child’s attention to the first problem on the page, 3 + 3, and
guide her to count the TouchPoints. Help her relate the problem to skip
counting (without the number line) as she points to each number, saying, “3,
6.” Then have her write the total, 6.

•In the second row, lead your student to put a finger on the first 3 and skip count
by threes to find that 3 groups of 3 equals 9. Continue in the same manner for
the rest of the repeated additions. You may also ask your student to say the
related multiplication fact for each repeated addition.
•Read together the word problems on the bottom half of the page. On the board,
write each repeated addition, its related multiplication sentence, and the
total as your student volunteers answers.

Adding within 100
Guided Practice: Activity Sheet 66
Name
•Tell your student that on this page he will add two-digit numbers with and
without regrouping. Lead him to notice that the boxes are no longer there for
him to record when he regroups ones to tens. Show him how to add the box at
the top of the tens column to those problems he needs to regroup.
•Work the first problem, 43 + 37, together. Add the ones, and ask your student if
he will need to regroup. Elicit that since 7 + 3 is greater than 9, he will regroup
the 10 ones into 1 ten. Show your student how to draw the small box at the top
of the tens column, just above the 4, to record the 1 ten. Guide your student as
he records the 1 in the box and writes 0 in the sum in the ones column. Then
together add the tens, 1 + 4 + 3, and record 8 in the tens place in the sum. Say
together, “43 plus 37 equals 80.”
•Continue in the same manner for the rest of the problems in the first two rows.
Guide your student to draw boxes for those problems that require regrouping
(in row 1, problems 2 and 5, and in row 2, problems 2, 3, and 4).

Solving Subtraction Word Problems within 100
Guided Practice: Activity Sheets 88
•Tell your student that on this page she will solve subtraction word problems. She
can draw a picture of the problem or write a number sentence and solve it.
Name
There are 23 marbles in a jar.
15 marbles are red. 5 marbles are blue.
How many marbles are other colors?

•Read together the first problem. Ask what information is given that she will use
to solve the problem—23 marbles in the jar, 15 red marbles, 5 blue marbles, and
an unknown number of the other colors. Elicit suggestions of how to solve the
problem. Your student might suggest drawing 23 circles, coloring 15 of them
red and 5 blue, and then counting how many are not colored, 3. Or she might
suggest subtracting twice, 23 – 15 = 8 and 8 – 5 = 3. She may suggest adding first
and then subtracting, 15 + 5 = 20 and 23 – 20 = 3.
•Read together the rest of the problems, and encourage your student to share her
problem-solving strategies.
