2.OA.4 Multiplication Activities


Array City

This fun multiplication art project comes from Looking From Third to Fourth! Kids construct a city of arrays! Check out her site for details and a printable.

Here is a copy of the chart  from Looking From Third to Fourth!

 

YAY for ARRAYS!

2 player, dice game: Kids take turns rolling two dice. They use the numbers the dice land on to create an array on a grid, using number counters (or cheerios, paperclips, etc.). After they make their array, they write it down (ex: 2 rows of 4). Then, they write the multiplication equation down and solve it. They compare their answer to their opponent's. The player with the largest product wins and circles his answer. They continue playing. Then, when they're finished, they count up the total number of times they won. Whoever won the most is the overall winner!
 

Lego Multiplication: Groups of and Arrays

Make multiplication fun with legos! A lego brick represents one group. Kids count the studs to figure out the multiplication equation. For example 2 lego bricks with 4 studs (2 groups of 4) equals 2 x 4. Then, they solve it! (2 x 4 = 8) 





Kids can also find arrays on legos to help with their multiplication skills. When you look at the studs on top a lego, you see an array! Kids examine the rows to figure out the equation. For example, one lego brick with 8 studs (2 horizontal rows of 4 studs, 2 x 4 = 8)

Guess My Array

Homework: Have kids make a multiplication array at home using their favorite toy, snack, or any other object. Then, they bring their objects to class and set it up. Once arrays are ready to go, mix kids up and have them go around the classroom, writing multiplication equations and solving their classmates' arrays!
