Addition facts

Addition facts: a free Grade 1 math game for ages 6-7. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Addition facts sounds like a long list, but this Grade 1 game holds the same five cards every time: 0 + 0, 0 + 7, 1 + 8, 2 + 6 and 3 + 5. A round shows all five, each read aloud, and your child taps the answer among four nearby numbers. Every answer is checked.

A fact is a sum known without counting. These five touch three kinds: zero facts, a plus-one fact and sums close to a double. Because the cards repeat, the game works best as a quick warm-up that your child can master in a few rounds. Speed then comes from knowing, not from rushing.

On 1 + 8, the choices include 8 itself, and a child who reads the big number and forgets the one taps it. Plus one is the next number. Ask, "What comes right after 8?" Praise the knowing: "You knew that one straight away."

Aligned with

  • 1.NBT.C.4 Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
  • 1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
