HMH Into Math Grade 2 Module 11 Review Answer Key
Vocabulary
Question 1.
Draw lines to match the yellow part of the equation to the word.
Answer:
Explanation:
1. Addend : a number which is added to another,
here 2 is added to 50 so matched 52 = 50 + 2 with addend,
2. The addition is taking two or more numbers and
adding them together here 30 is added to 7 we get 37
so matched 30 + 7 = 37 with add,
3. To subtract means to take away from a group or a
number of things as 47 – 21 = 26 so matched with subtract.
Concepts and Skills
Question 2.
Make a new group of ten. Complete the equations to solve.
Answer:
27 + 5 = 32,
Explanation:
Given to solve 27 + 5 we break apart
5 into 3 and 2 so that we can make a new ten
group so that 27 + 3 + 2 becomes
30 + 2 = 32,therefore 27 + 5 = 32.
Question 3.
Break apart ones to subtract. Complete the equations to solve.
Answer:
Explanation:
Given 46 -9 while subtracting I broke apart 9 ones to make a
tens number so I subtract as 46 – 6 – 3,
40 – 3 = 37, therefore 40 – 3 = 37.
Question 4.
Break apart the addends into tens and ones. Find the sum.
Answer:
Explanation:
Given 33 + 21,
Breaking apart the addends into tens and ones to solve as
33 –> 30 + 3
21 –> 20 + 1
50 + 4 = 54
therefore, 33 + 21 = 54.
Question 5.
Break apart the number you are subtracting into tens and ones.
Find the difference.
Answer:
Explanation:
Given 49 – 12 breaking apart the number we are
subtracting into tens and ones.
Subtracting the tens, then subtract the ones to find the difference as
49 – 12,
49 – 10 = 39,
39 – 2 = 37, therefore 49 – 12 = 37.

we break by tens and ones as 40 + 5,
so matches with (c) 40 + 5.
Question 7.
Which shows how to break apart 26?
(A) 200 + 60
(B) 20 + 6
(C) 60 + 60
Answer:
(B) 20 + 6,
Explanation:
Given to show break apart 26,
we break by tens and ones as 20 + 6,
so matches with (B) 20 + 6.
Question 8.
Which shows how to break apart 58?
(A) 50 + 8
(B) 50 + 80
(C) 5 + 8
Answer:
(A) 50 + 8,
Explanation:
Given to show break apart 58,
we break by tens and ones as 50 + 8,
so matches with (A) 50 + 8.
