Today we lay out counters to build the fact I call out. Everyone builds at their own desk at the same time as the pupil building it on the board, so keep your counters ready. We'll build these together, one at a time: 2 rows of 5, then 4 rows of 3, then 5 rows of 2, and finally 6 rows of 3. For each one we say the repeated addition first, then the multiplication, then read the total off the array.

Today we work through these arrays together on the board: build 2 × 6, then 3 × 5, then 4 × 6, and finally a different rectangle that has the same total as 4 × 6. That last one is the thinking one.
