Array Multiplication Mat

Use a muffin tin or egg carton to model arrays.

Array multiplication mat.

To see this you can calculate the product of two matrices. This operator multiplies each element of the first matrix by the corresponding element of the second matrix. Multiply the matrices by using the elementwise multiplication operator. This mat is designed to help students represent division using various models.

Create arrays using connect four. They will use the repeated subtraction strip diagrams groups of arrays and number lines. If the sizes of a and b are compatible then the two arrays implicitly expand to match each other. It makes sense of your times tables.

Using a twister mat can be such a fun way to practice math facts but it can also be used to create huge multiplication arrays. Learn to multiply using arrays. 2 x 4 and 4 x 2. To make the egg carton more versatile tape several together.

A regular muffin tin mini muffin tin or egg cartons can be easy ways to display objects in an array. The sizes of a and b must be the same or be compatible. Print the division models mat in color on white cardstock. The dimensions of the matrices must be the same.

An array is a group of shapes arranged in rows and columns rows run left and right and columns go up and down you can write a. C a b multiplies arrays a and b by multiplying corresponding elements. Upgrade to math mastery. For example an array shows that when multiplying two numbers together the order of those numbers can be switched around.

The multiplication strategy mat requires the child to draw make and write to represent a multiplication problem as four different strategies equal groups arrays repeated addition and skip counting as well as recording the problem with the correct answer as a complete number sentence. The matrix multiplication operator calculates the product of two matrices with the formula c i j k 1 n a i k b k j.
