Solve Facts with Arrays

Students use arrays to solve multiplication facts, check commutative pairs, and build fact-family fluency.

Solve Facts with Arrays

What students learn

Students learn to use arrays to solve multiplication facts and check answers. Start with so students can see how an array leads to a product.

Why it matters

Arrays help students build fact fluency without blind memorization. They can use one picture to solve several related facts and check whether their answer makes sense. Use to reinforce the link between the array and the product.

Learn the idea

If a child knows 3 x 4, they can also think about 4 x 3 by flipping the array. Watch and ask how the same objects can show a new fact.

Try it

Give the student an array fact card and ask them to write the multiplication sentence, the repeated addition sentence, and the turn-around fact. Then replay and have them explain one fact family from start to finish.

Parent guide

Practice with small facts first, such as 2 x 3, 3 x 4, and 4 x 5. Ask the child to explain the array out loud before writing anything. If they get stuck, let them draw dots in rows. The goal is to make the picture do the work, not the memory alone.
