Multiply to Count Arrays: what children learn
An array puts equal groups in neat rows and columns, so the total is rows × columns. A 3 by 4 array has 3 rows of 4, and 3 × 4 = 12.
Multiply to Count Arrays: worked example
An array has 3 rows of 4 dots. How many dots are there in all? 12
3 rows of 4 is 3 × 4 = 12 dots.
Multiply to Count Arrays: a common mistake to watch for
Kids sometimes add the rows and the columns instead of multiplying them.
Multiply to Count Arrays: how to help at home or in class
An egg carton, a muffin tin or an ice cube tray is a ready-made array. Ask your child to count the rows and the columns, say what the total should be, and only then check by counting. Turn the object a quarter turn so the rows and columns swap while the total stays put. Once your child predicts totals by multiplying instead of counting each item, writing the matching sentence is the next skill.
