  1. Fact Triangles 9 x, ÷ 3 3

  2. What are Fact Triangles? • Fact Triangles are tools that can help you memorize your basic facts. • The “x, ÷” printed on the card means that it is used to practice multiplication and division facts. • The “*” symbolizes the product of the other two numbers. • The four number sentences developed from the triangle are called fact families.

  3. What is this triangle’s Fact Family? 3 x 3 = 9 3 x 3 = 9 9 ÷ 3 = 3 9 ÷ 3 = 3 *9 x,÷ 3 3

  4. What is this triangle’s Fact Family? 3 x 2 = 6 2 x 3 = 6 6 ÷ 2 = 3 6 ÷ 3 = 2 *6 x,÷ 3 2

  5. What is this triangle’s Fact Family? 6 x 1 = 6 1 x 6 = 6 6 ÷ 1 = 6 6 ÷ 6 = 1 *6 x,÷ 6 1

  6. What is this triangle’s Fact Family? 1 x 0 = 0 0 x 1 = 0 0 ÷ 1 = 0 1 ÷ 0 = 0 *0 x,÷ 1 0

  7. What is this triangle’s Fact Family? 4 x 3 = 12 3 x 4 = 12 12 ÷ 3 = 4 12 ÷ 4 = 3 * 12 x,÷ 4 3

  8. What is this triangle’s Fact Family? 3 x 10 = 30 10 x 3 = 30 30 ÷ 3 = 10 30 ÷ 10 = 3 * 30 x,÷ 3 10

  9. What is this triangle’s Fact Family? 2 x 2 = 4 4 ÷ 2 = 2 Why are there only 2 number sentences? *4 x,÷ 2 2

  10. What is this triangle’s Fact Family? 5 x 10 = 50 10 x 5 = 50 50 ÷ 5 = 10 50 ÷ 10 = 5 * 50 x,÷ 5 10

  11. What is this triangle’s Fact Family? 2 x 5 = 10 5 x 2 = 10 10 ÷ 2 = 5 10 ÷ 5 = 2 * 10 x,÷ 2 5

  12. What is this triangle’s Fact Family? 3 x 5 = 15 5 x 3 = 15 15 ÷ 5 = 3 15 ÷ 3 = 5 * 15 x,÷ 5 3

  13. What is this triangle’s Fact Family? * 16 4 x 4 = 16 4 x 4 = 16 16 ÷ 4 = 4 16 ÷ 4 = 4 x,÷ 4 4

  14. What is this triangle’s Fact Family? 5 x 5 = 25 25 ÷ 5 = 5 Why are there only 2 number sentences? * 25 x,÷ 5 5

  15. What is this triangle’s Fact Family? 4 x 5 = 4 5 x 4 = 4 20 ÷ 5 = 4 20 ÷ 4 = 5 * 20 x,÷ 4 5

  16. How do find a missing number on a Fact Triangle? • If one number is not there, you need to figure out what number is missing. • If the “*” number is missing, we know that if you multiply the other two numbers it equal the “*”. • If another number is missing, you take the “*” number and divide the other number given to find the missing number. Let’s try a few!

  20. What is this triangle’s Fact Family? * 12 3 x = 12 x 3 = 12 12 ÷ 3 = 12 ÷ = 3 4 4 4 x,÷ 4 3 4

  21. What is this triangle’s Fact Family? x 0 = 0 0 ÷ = 0 3 *0 3 x,÷ 3 0

  22. What is this triangle’s Fact Family? 8 2 x 4 = 4 x 2 = ÷ 2 = 4 ÷ 4 = 2 * 8 8 8 x,÷ 8 4 2

  23. What is this triangle’s Fact Family? * 7 7 x = 7 x 7 = 7 7 ÷ 7 = 7 ÷ = 7 1 1 1 x,÷ 1 7 1

  24. What is this triangle’s Fact Family? x 2 = 4 2 x = 4 4 ÷ = 2 4 ÷ 2 = 2 *4 2 2 x,÷ 2 2 2

  25. What is this triangle’s Fact Family? 16 4 x 4 = 4 x 4 = ÷ 4 = 4 ÷ 4 = 4 * 16 16 16 x,÷ 16 4 4

  26. What is this triangle’s Fact Family? * 20 10 x = 20 x 10 = 20 20 ÷ 10 = 20 ÷ = 10 2 2 2 x,÷ 2 10 2

  27. What is this triangle’s Fact Family? 14 7 x 2 = 2 x 7 = ÷ 7 = 2 ÷ 2 = 7 * 14 14 14 x,÷ 14 2 7
