Math

Grade 2 class' goals for learning multiplication is to learn to skip-count rhythmically by 3, 4, 6, and 9 this year. Afterwards, we will practice 7's and 8's. They learned 1, 2, 5, and 10 last year. Some students have found that the 11's are quite easy and already know them well.
When they look at a grid, they are able to count two sides and figure out which two numbers they need to multiply.

OOOOOOO
OOOOOOO
OOOOOOO
OOOOOOO
The figure shows 4 X 7, which is 28.
Some students like to picture the multiplication problem in terms of rows of an item, and a certain number of items in each row. The Math book demonstrates this example well.

3 X 4 = 3 rows of 4, therefore:

OOOO
OOOO
OOOO
