Question 2: Use the subtracting back using a number line strategy to solve the following word problem. Tony bought a baseball glove for $63. He gave the cashier $100. How much money would he have left after he bought the glove?
Question 3: Use the decomposing by place value strategy to solve the following word problem. Carla had a collection of 821 paper clips. She used 287 paper clips in a science project. How many paper clips are still in Carla’s collection?
Question 4: Your turn. Think about a time when you have had to use subtraction in real life. Write a subtraction word problem based on that time and solve using one of the 3 strategies (adding up, subtracting back using a number line, decomposing by place value). Be sure to have the word problem written on the paper that you upload.
