About this worksheet

Some first grade problems combine three small amounts instead of two. The new challenge is not larger arithmetic alone; it is choosing an efficient order and keeping track of all three parts. Children often add the first two numbers and forget the third, or they try to count everything one by one when two numbers can make ten. This worksheet gives short stories with three groups, then asks learners to find a total, choose a matching equation, or identify the pair that should be grouped first. Support pages keep sums near ten. Standard and challenge pages include totals to twenty and more make-ten opportunities. The goal is careful modelling with three addends, not memorizing a trick. Ask your child to circle all three quantities and place a tiny check mark as each one is included in the sum.

What your child will learn

  • Add three numbers in a story
  • Group numbers that make ten
  • Write an equation with three addends
  • Track every part of the problem

Worked example

There are 6 red buttons, 4 blue buttons, and 3 green buttons. Six and four make ten, then three more makes 13.

Common mistake

Adding only two of the three groups because the first partial total feels finished.

Helpful hint

Circle all three numbers and check them off as you add.
