Making 10 · Learner pages

Lesson 1 · Fill a ten-frame

Find how many more counters make ten.

Name or initials: ____________   Date: ____________

Touch each counter once as you count. A ten-frame has 10 places: two rows of five.

1. Count the filled places. There are 6 counters. Count them once, from left to right.
2. Look for empty places. Four of the ten places are empty.
3. Fill every place. Add 4 counters. Now all 10 places are filled.
4. Say the number sentence. Six and four make ten: 6 + 4 = 10.

Worked example: I have 7 counters. Three places are empty. Add 3: 7 + 3 = 10. Check by counting all ten.

1. You have 8 counters. How many more make 10?

   1. 1 · 2. 2 · 3. 3

2. Which pair makes 10?

   1. 5 and 4 · 2. 6 and 5 · 3. 5 and 5

3. There are 10 counters. You remove 3. How many are left?

   1. 7 · 2. 8 · 3. 6

Discuss: Draw a ten-frame. Ask a partner to put in 8 dots, then find how many dots are missing.

Lesson 2 · Build ten and some more

Show numbers from 11 to 19 as ten and extra ones.

Name or initials: ____________   Date: ____________

A full ten-frame is one group of ten. Extra counters are ones.

1. Make one ten. Fill all ten places. Keep this group together.
2. Count extra ones. Place 4 more counters beside the frame.
3. Combine the groups. Ten and four make fourteen. Write 10 + 4 = 14.
4. Read the digits. In 14, the 1 stands for one ten and the 4 stands for four ones.

Worked example: To show 17, fill a ten-frame and add 7 counters: 10 + 7 = 17. One ten and seven ones make seventeen.

1. One ten and 3 ones make…

   1. 13 · 2. 4 · 3. 30

2. Which shows 18?

   1. 8 tens and 1 one · 2. 1 ten and 8 ones · 3. 1 ten and 7 ones

3. How many extra ones go beside a full ten-frame to make 15?

   1. 15 · 2. 10 · 3. 5

Discuss: Use drawings to show 12 and 16. Circle the group of ten in each drawing.

Lesson 3 · Compare two teen numbers

Use extra ones to compare numbers from 11 to 19.

Name or initials: ____________   Date: ____________

When two numbers each have one ten, compare the extra ones.

1. Build the first number. Fourteen is one ten and four ones.
2. Build the second number. Seventeen is one ten and seven ones.
3. Compare the extra ones. Both have one ten. Seven extra ones are more than four.
4. Say the comparison. Seventeen is greater than fourteen. Fourteen is less than seventeen.

Worked example: Compare 12 and 15. Both have one ten. Five ones are more than two ones, so 15 is greater than 12.

1. Which is greater?

   1. 12 · 2. 16 · 3. They are equal

2. Which is less than 15?

   1. 18 · 2. 17 · 3. 13

3. Arrange from least to greatest.

   1. 11, 14, 18 · 2. 18, 14, 11 · 3. 14, 11, 18

Discuss: Make 11 and 19 using drawings. Point to the same ten in both, then explain which has more.
