Square Numbers Introduction

Visual introduction to square number patterns . Useful as a visual introduction to exploring square numbers and/or as a lesson starter.

A square is slowly built by adding the next odd number of squares to the first to make a bigger square (number).

3 animated slides (don't bore your students too much, just use 1 a lesson)

*Slide 1 uses a growing pattern of odd numbers in an addition sentence (underneath the square) to create square numbers.
*Slide 2 uses the above plus the matching multiplication sentence.
*Slide 3 uses the visual and only the multiplication sentence.

I like to show slide 1 with just the addition sentence first off and impress my students with my quick fire maths skills ;-) "1+3+5+7+11+13+15+17+19+21+23 = 135". The following day I'll teach them the trick of multiplication. A few of my higher ability will be able to answer the addition sentences on their own at the end of a lesson.

You'll need a bit of patience as the squares reveal themselves.

Hope students around the world enjoy it (?) and that it makes multiplication that little more understandable.
