Writing arrays as addition equations W1-mt_B1zj1RwQ3a-s1

  1. 8 · 2 + 2 + 2 + 2 = 8 apples.
  2. 6 · 2 rows of 3 is 3 + 3 = 6.
  3. 5 + 5 = 10 · There are 2 rows, so you add 5 two times: 5 + 5 = 10.
  4. True · 4 rows means you add 3 four times: 3 + 3 + 3 + 3 = 12.
  5. 25 · Five rows of 5 hold 5 + 5 + 5 + 5 + 5 = 25 dots.
  6. 4 rows with 3 in each row · The equation has 4 addends of 3, so the array needs 4 rows with 3 objects in each row.
  7. 2 + 2 + 2 + 2 + 2 · Five rows of 2 add five 2s: 2 + 2 + 2 + 2 + 2 = 10.
  8. True · True. Equal rows are what makes an array an array.
  9. 5 rows of 4 · Count the addends: there are five 4s, so the array has 5 rows with 4 in each row.
  10. 24 · 4 rows of 6 is 6 + 6 + 6 + 6 = 24.
