A graph that uses bars of different heights to represent information.

The result of subtracting one number from another. Way in which two or more things we are comparing are not the same.

To partition one part from another (the subtrahend from the difference), or to decrease an amount by taking an amount away.

Calculate the difference when information is presented in a bar chart

Maths

In this unit pupils will add 3 addends. They will use a strategy such as finding 2 addends to total 10 or 2 numbers to bridge though 10.  In the future unit pupils will add and subtract 1s and 10s from 2 digit numbers. They will use number facts to add/subtract a single-digit number to/from a 2-digit number .They will use a part-part-whole model to represent addition and subtraction.

In the prior unit pupils revisited addition and subtraction within ten. They consolidated addition and subtraction strategies. In this unit pupils will add 3 addends. They will use a strategy such as finding 2 addends to total 10 or 2 numbers to bridge though 10.
