How the lesson starts: Equal Groups and Arrays

1. Lily's neat garden

   Hello! Lily the gardener loves neat rows and equal pots. Today she plants flowers in groups. Let's learn a smart way to count them!

2. Equal groups

   Lily has 3 pots of sunflowers. Each pot has 4. Every pot has the same number, so these are equal groups! If one pot had 5, they would not be equal. Count by fours: 4, 8, 12.

3. Rows and columns

   Now Lily plants an array. Rows go across. Columns go up and down. This garden has 3 rows and 4 columns. Each row has 4 tulips.
