Multiplication Mania

This month we started learning our multiplication facts. To start out the unit we learned a few different strategies to get the answers.

3x4=12
3 equal groups of 4 = 12

Drawing pictures

Repeated addition
3+3+3+3=12 or 4+4+4=12

Drawing Arrays

Fact Family
3x4=12
4x3=12
12 divided by 4=3 (no division sign, haha)
12 divided by 3=4

We have started passing off our facts and have passed off 0's, 1's, and 2's.

Tomorrow we will be passing off our 3's.
Thursday we will be passing off our 4's.
Friday we will be passing off our 5's.

When we get back from Thanksgiving break we will be passing off 6-11's. Please make sure your child is practicing their facts each night for at least 10 minutes. We will be continuing to practice our facts for the rest of the year, but are passing them off by Christmas.

Here is a free download for a multiplication game on the computer that helps with 2's-11's.

"I Am Not A Turkey!"

What do you get when you give your students a blank turkey, and tell them to disguise the turkey?


You get some of the following:
Miley Cyrus
A Police Woman
A Snowman
A Army Dude
A Raven
A Soccer Player
A Strawberry
A Pumpkin
President Obama
and more.... Take a look at these awesome "Turkeys"

Making Arrays

Another way we have been learning how to figure out multiplication answers is by drawing and making arrays. We took a 6x8 array, and cut it into 2 pieces. We had a bunch of different arrays, but when put together, they all equaled 48.

Multiplication Game with Dice

Our class loves playing math games, and it is a great way for the students to discover the answers on their own. If you have some dice at your house, play this game for some extra practice! (It will count towards your 10 minutes of practice each night.)

You can pick a number to times by, we picked 3's yesterday. And then roll one or two dice and times the number you rolled, with the 3.
