Question 1.
Write an equation to match each cube train.
ex:
a.
Answer:
Addition equation:
4 + 3 = 7.
Explanation:
Number of shaded cubes = 4.
Number of unshaded cubes = 3.
Total number of cubes = Number of shaded cubes + Number of unshaded cubes
= 4 + 3
= 7.
b.
Answer:
Addition Equation:
6 + 1 = 7.
Explanation:
Number of shaded cubes = 6.
Number of unshaded cubes = 1.
Total number of cubes = Number of shaded cubes + Number of unshaded cubes
= 6 + 1
= 7.
c.
Answer:
Addition Equation:
4 + 3 = 7.
Explanation:
Number of shaded cubes = 4.
Number of unshaded cubes = 3.
Total number of cubes = Number of shaded cubes + Number of unshaded cubes
= 4 + 3
= 7.
Question 2.
Color in the cube train to match the equation.
ex:
a. 2 + 5 = 7
Answer:
Explanation:
Addition Equation:
Number of yellow cubes = 2.
Number of blue cubes = 5.
Total cubes in the train = Number of yellow cubes + Number of blue cubes
= 2 + 5
= 7.
b. 1 + 3 + 3 = 7
Answer:
Explanation:
Addition Equation:
Number of yellow cubes = 1.
Number of green cubes = 3.
Number of blue cubes = 3.
Total cubes in the train = Number of yellow cubes + Number of blue cubes
= 1 + 3 + 3
= 4 + 3
= 7.
c. 7 + 0 = 7
Answer:
Explanation:
Addition Equation:
Number of red cubes = 7.
Number of blue cubes = 0.
Total cubes in the train = Number of red cubes + Number of blue cubes
= 7 + 0
= 7.

7 – 3 = 4.
6 – 4 = 2.
7 – 5 = 2.
6 – 3 = 3.
7 – 7 = 0.
6 – 1 = 5.
Explanation:
Given equations:
Subtraction:
7 – 0 = 7.
6 – 2 = 4.
7 – 6 = 1.
7 – 2 = 5.

7 – 5 = 2.
6 – 3 = 3.
7 – 7 = 0.
6 – 1 = 5.
Question 4.
Fill in the missing numbers.
3 + _____________ = 7
___________ + 5 = 7
7 = 6 + _____________
7 = 4 + ______________
Answer:
3 + 4 = 7
2 + 5 = 7
7 = 6 + 1.
7 = 4 + 3.
Explanation:
Missing numbers:
3 + ?? = 7.
=> ?? = 7 – 3
=> ?? = 4.
?? + 5 = 7.
=> ?? = 7 – 5
=> ?? = 2.
7 = 6 + ??
=> 7 – 6 = ??
=> 1 = ??.
7 = 4 + ??
=> 7 – 4 = ??
=> 3 = ??.
Question 5.
Tammy has 14 pennies. Troy has 5 pennies. How many more pennies does Tammy have than Troy?
Tammy has ______________ more pennies than Troy.
Answer:

= 14 – 5
= 9.
Question 6.
CHALLENGE Some bikes and trikes are on the playground. There are 7 seats and 19 wheels. How many bikes are there? How many trikes are there? Show your work.
There are ______________ bikes on the playground.
There are ______________ trikes on the playground.
Answer:
There are 2 bikes on the playground.
There are 5 trikes on the playground.
Explanation:
Number of seats = 7.
Number of wheels = 19.
Number of vehicles = Number of wheels ÷ Number of seats
= 19 ÷ 7
= 2 quotient and 5 remainder.
Number of wheels of bike = 2 × 2 = 4.
Number of wheels of trike = 5 × 3 = 15.
