3rd graders have been using this site: Kids math games online, and I just tried out the activities too!
In the multiplication area pictured below there are four choices. Each one has an activity to help with multiplication facts and learning fact families. The red one called Learn Multiplication has bright colors that change and flash, which was a bit much for me, but kids are sure to love it!
The bottom one called Multiply Numbers comes from the Hooda Math site. After finishing the activity, you go directly to Hooda Math where you can try one of their games, or use the browser's back button to come back to this page.
