Big Ideas: Estimation can be a tool to solve two-step word problems. We can solve one and two-step word problems using “how many more” and “how many less” using the graph. There are many different ways to solve a single and multiple-step word problem. We can assess our answers by investigating and developing arguments. Students will use data presented in a data table to calculate estimated answers to two-step problems. Students share their strategies with classmates and begin to realize there are multiple ways to find a reasonable answer using estimation. Vocabulary: estimate, estimation, total, benchmark numbers
