Module 5:
"Addition and Subtraction within 1,000 with Word Problems to 100"
"Addition and Subtraction within 1,000 with Word Problems to 100"
In this module, students:
What can you do at home to support the learning in this module?
- Increase fluency when adding and subtracting with two- and three-digit numbers by having two ways to solve problems, including using checking subtraction using addition.
- Solve one-step and two-step word problems that involve two-digit addition and subtraction.
What can you do at home to support the learning in this module?
- Encourage your child to explain her mathematical thinking when doing homework or playing math games. "How did you solve that problem? Can you explain your thinking to me?"
- Ask your child how many ones, tens, and hundreds are in numbers that you and your child come across, and what happens if you take a one or a ten or a hundred away, or if you add a one or a ten or a hundred. "How many hundreds are there in 792? What happens if I add a hundred? What happens if I take away a one?"
- Continue to practice counting by tens from any number to any number within 1000, and try counting by hundreds from any number. "Let's count by hundreds from 83 to 783."
