Equal Schmequal

We have been learning about balance scales in maths. A balance scale acts like a seesaw. A heavier weight pushes down and lifts the lighter side up.

We read the story 'Equal Schmequal' by Virigina Kroll. It is about some animals who are trying to figure out how to get fair teams for tug of war. They use a seesaw to balance out their weights.

We had lots of fun using balance scales at school to find out the weights of different things. We have been using words like 'lighter', 'heavier', 'equal to', and 'balanced'. Our teacher might put more photos up of this later.

Just like a seesaw or balance scale can find equal weights, we have learnt that you can also have balanced numbers. We looked at this problem:

We know that 9 and 1 makes 10. So if there were 3 marbles in the yellow bag, there would need to be 7 marbles in the blue bag to make 10 altogether. That would make the two sides balanced or equal.
We checked using real marbles on our set of balance scales. We were right!

We then made up our own balanced numbers. Have a look at how we did!

This is our first time doing this with numbers. We know we are only going to get better at doing this! Maybe you could do some with us at home! :)
