How many trucks and trains are there?
HMH Into Math Grade 1 Module 3 Lesson 2 Answer Key Add in Any Order 5
Answer:

Explanation:
There are 2 trucks
There are 9 trains
The sum of 2 and 9 is 11

Step It Out

1. How can one addition fact help you know another addition fact?
A. What is 9 + 2?
THINK: Start at 9 Count on 2.
9, ___, ____
So, 9 + 2 = ____
B. If you know 9 + 2 = 11, what other addition fact do you know?
