Picture a bakery tray of fresh buns. There are 3 rows, and each row holds 5 buns. How many buns are on the whole tray? And here is the real question: is there a quicker way to find out than pointing at each bun one at a time?

Look at each array of coloured tiles on the interactive. Read every array two ways with me, as repeated addition, then as a multiplication. Keep your eye on the last pair: the same tiles, but turned.

Today we build arrays together on the board and read each one two ways. We will do 4 rows of 3, then turn it to 3 rows of 4; then 2 rows of 6, then turn it to 6 rows of 2. Each time, build it, read the repeated addition aloud, then say the multiplication and check the total.
