We are starting work with Multiplication this month.
One of the main ways we teach Multiplication is through skip counting.
You can help your 3rd grader by skip counting with them.
Start with the easier numbers (2's, 5's, 10's) When they can say them quickly through 100 move on to 3's, 4's, 6's, 8's & 9's
If they are struggling, you can help them by saying every other number.
