Teaching Notes

This collection focuses on sequential addition, requiring learners to solve each step before moving to the next. Emphasize showing intermediate calculations to track progress and identify errors.

Vocabulary
Number Chain: A sequence of numbers to add.
Sequential: One after another in order.
Common Mistakes
  • Calculation errors in a step
  • Losing track of the current sum
  • Rushing through steps without showing work
Differentiation
SupportUse a number line or manipulatives. Break chains into fewer, smaller steps.
ChallengeIncrease number of steps/digits. Introduce missing addends in a chain.
Discussion Questions
  • Why is it important to show your work?
  • What strategy do you use to keep track of the current sum?
  • How is adding a chain of numbers different from adding two numbers?
  • Can you think of a real-life situation where you might add numbers in a chain?
Extension Activities
  • Use larger numbers.
  • Add and subtract in chains.
  • Create your own chains.
Parent Tip

Give your child a list of numbers to add up, one by one.
