Lesson Two

Terrific Tuesday!!!

 

STARTER:  Count forwards and backwards in 2s, 5s and 10s.

 

Today we are going to review what an array is.

 

What Is An Array In Maths?

 

An array in maths is an arrangement of objects, numbers or pictures in columns or rows. The purpose of an array is to help us to understand multiplication and division.

 

We already know that multiplication is commutative.  This means we can show the multiplication of two numbers can be done in any order.  e.g. 3 x 5 = 15    5 x 3 = 15.

 

The language that we use for multiplication is 3 lots of 5 or 5 lots of 3.  We might also say 3 groups of 5 or 5 groups of 3. So we are going to review how we show our multiplication by drawing an array and writing the number sentence.   See the picture below.

Task One: 

Remember those cards we made with number 1 - 9 on, we're going to need them again.  You will need to have three more that say 10, 11, 12 and one with an X on it.

 

Pick two cards and place them on either side of the X.  You now have a multiplication sentence.   Now create an array for it.  You can use pasta, beads, teddy bears, lego or counters or even small cars.  Get creative and have some fun with it.   See the pictures below!
