Math Happennings

This week we started division. We grouped two-digit numbers into single-digit groups using manipulatives, grid paper and pictures. It was a lot of fun!!

Fact Fluency

We have been discussing multiplication strategies in class and will continue to do so. We are also learning some fun games to help them master their facts.

This week we will be reviewing strategies for solving facts from 0-6. Practice makes permanent!

Please encourage your students to study their facts for 10-15 minutes a day!!

Here are some ideas to practice facts at home:

-Have your student make a set of flash cards using note cards or construction paper.

-Quiz them in the car (or during any down time) over random facts from 0-12

-If you have a deck of playing cards at home ask your student to show you how to play "Spiral Multiplication." It's really fun!

Prefer to use technology? There are also a lot of great apps and games on the computer to help with facts too!

Try some of these:

-Hooda Math Flash Cards (app), they also have a lot of online games.

-Big Brainz- a virtual computer game game (costs money for the full version, but there is a free trial) It also has addition and subtraction in bets right now if you have younger kiddos

-Know Your Math Facts App- free on iTunes


-Rocket Math- $.99 on itunes

-Multiplication Training- free on itunes

-Times Table Quiz- free on itunes

-Sushi Monster- free on iTunes

And I'm sure there are tons more! Let me know if you find any good ones that I can use in the classroom and I will let you know if I find some good apps or computer games:)
