**Bridges in Mathematics Grade 1 Home Connections Unit 3 Module 1 Session 2 Answer Key**

**Double It**

Note to Families

Your child has played this game in school and should be able to teach you how to play! There is a regular game (players double the numbers 1-6) and a challenge game (players double the numbers 1-10).

Materials

- Double It pages 1-3
- game markers—any small item will do: pennies, dry beans, Legos, and so on (6 of each for the regular game; 10 of each for the challenge game)
- pencil and a paperclip to be used as a spinner arrow

**Instructions**

1. Choose one of the game boards and collect your game markers.

2. Use the paperclip as an arrow. While holding the pencil point down in the middle of the spinner, spin the paperclip around it.

3. Take turns spinning the spinner, doubling the number, and covering the sum on your side of the game board. (For example: If you spin 3, double it to 6, and cover the 6 on the game board.)

4. If you spin a number that you have already covered, you will have to wait until your next turn to try again.

5. The first person to cover all six of their numbers is the winner!

6. **CHALLENGE** For the Double It Challenge game, you need to spin the 0-5 spinner twice, add the numbers, and then double the sum. (For example, if you spin 3 and 5, you add them to get 8 and then double 8 to get 16. Cover the number 16 on your game board.)

Question 3.

Solve the problems below.

a.

Answer:

Explanation:

Number of dots given in first line = 1.

Number of dots given in second line = 1.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 1 + 1

= 2.

b.

Answer:

Explanation:

Number of dots given in first line = 1.

Number of dots given in second line = 2.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 1 + 2

= 3.

c.

Answer:

Explanation:

Number of dots given in first line = 2.

Number of dots given in second line = 2.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 2 + 2

= 4.

d.

Answer:

Explanation:

Number of dots given in first line = 2.

Number of dots given in second line = 3.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 2 + 3

= 5.

e.

Answer:

Explanation:

Number of dots given in first line = 3.

Number of dots given in second line = 3.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 3 + 3

= 6.

f.

Answer:

Explanation:

Number of dots given in first line = 3.

Number of dots given in second line = 4.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 3 + 4

= 7.

g.

Answer:

Explanation:

Number of dots given in first line = 4.

Number of dots given in second line = 4.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 4 + 4

= 8.

h.

Answer:

Explanation:

Number of dots given in first line = 4.

Number of dots given in second line = 5.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 4 + 5

= 9.

i.

Answer:

Explanation:

Number of dots given in first line = 5.

Number of dots given in second line = 4.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 5 + 4

= 9.

j.

Answer:

Explanation:

Number of dots given in first line = 5.

Number of dots given in second line = 5.

Total number of dots given = Number of dots given in first line + Number of dots given in second line

= 5 + 5

= 10.

Question 4.

Fill in the blank to complete each equation.

3 + 4 = ____ 4 + 5 = ____ 2 + 3 = _____ 5 + 6 = _____

4 + _____ = 8 2 + _____ = 4 3 + _____ = 6 5 + _____ = 10

10 – 5 = ______ 6 – 3 = _____ 8 – 4 = ______ 4 – 2 = ________

Answer:

3 + 4 = 7. 4 + 5 = 9. 2 + 3 = 5. 5 + 6 = 11.

4 + 4 = 8 2 + 2 = 4. 3 + 3 = 6. 5 + 5 = 10.

10 – 5 = 5. 6 – 3 = 3. 8 – 4 = 4. 4 – 2 = 2.

Explanation:

Addition:

3 + 4 = 7.

4 + 5 = 9.

2 + 3 = 5.

5 + 6 = 11.

4 + ?? = 8

=> ?? = 8 – 4

=> ?? = 4.

2 + ?? = 4

=> ?? = 4 – 2

=> ?? = 2.

3 + ?? = 6

=> ?? = 6 – 3

=> ?? = 3.

5 + ?? = 10

=> ?? = 10 – 5

=> ?? = 5.

10 – 5 = 5.

6 – 3 = 3.

8 – 4 = 4.

4 – 2 = 2.

Question 5.

**CHALLENGE** Fill in the blank to complete each equation.

Explanation:

Given equations:

Addition:

40 + 30 = 70.

50 + 40 = 90.

50 + 60 = 110.
