I love my magnetic

whiteboard!

Large Arrays

I copied and laminated enough of these templates for each student in my classroom, and placed them in manilla file folders. I also placed base ten blocks in plastic baggies. This makes it simple to quickly hand out the materials and get started on the activity.

My students enjoy creating their own large arrays.

Here are a few of our large arrays. My students label each section of the array. When they are finished with the large array, the children use the distributive property to check their answers at the bottom.

"The Properties"

Commutative, Associative, and Distributive properties of multiplication.

My students created

their own designs to

model the

Commutative

and

Associative Properties

I thought this design for

the Associative Property

was very creative.

It's hard to believe that a 9 yr. old

can draw this well, but, she can!

I am particularly fond of the football jersey models of the properties. My son is the kicker for our high school football team and his number is 5. This child always goes to the football games and the other 2 numbers he is modeling are our 2 of our team's starters...one of which is his cousin. I think this is a good example of using prior knowledge to problem-solve :)

When my class gets to larger multiplication problems, I use a grid that I purchased from a school supply store years and years ago. I placed magnets on the back of the grid to use on my magnetic whiteboard.

I begin by placing a post-it note on the digit on the second row that is not being multiplied. Then I switch the post-it to the other digit and multiply.

This way the students do not become confused.

grid paper at their desks. (This centimeter grid paper is large enough to write a digit in each square.) The grid paper guides students to place the digits in the correct columns and keep them aligned correctly.

I have my students cut out a single centimeter square at the bottom of the grid to cover the digits not being used on their own grid paper. (I have shaded in the centimeter square so you can see it on the picture above.)

Birds of a Feather

This is a 2 x 2 digit multiplication activity. It takes a while for the students to finish. First, the students work out 24 problems on notebook paper, then transfer the answers to the Birds of a Feather handout. Finally, the

they cut and paste the birds onto the handout. The directions tell which birds go with which numbers.

As you can tell by the notebook paper laying on the corner of the desk, there is a lot of work involved with this multiplication activity.

iPad Time!

Since learning multiplication times tables is not a 4th grade standard, I try to work in as much time as I can anyway to let the students practice them...because we all know that even though they are supposed to have mastered the times tables in 3rd grade, it is a myth that they will know them all in 4th grade. One way we occasionally practice is with the iPads. Our school has a couple of class sets of these, so, whenever I can get my hands on them, we use them. The kids absolutely love them.

Our computer teacher placed several times tables' activities on the iPads.

Of course, sometimes my kids get off task :)

(I don't mind nearly as much when they are off task, if it is a present for me!)

Would love to know the multiplication apps that are shown in the pictures. I find it hard to find apps that I like, honestly.
