These maze activities help children to identify angles on a straight line and half a turn (total 180°). The first worksheet is aimed at those working towards age expected. Children work out the unknown angle on a straight line. Includes multiples of 10. The second worksheet is aimed at those working at age expected. Children work out the unknown angle on a straight line. Includes multiples of 5 and 10. The third worksheet is aimed at those working at greater depth. Children work out the unknown angle on a straight line. Includes more than two steps addition. Children should recognise that a half turn is the same as a straight line, meaning that adjacent angles on a straight line sum to 180°. Looking at a protractor will reinforce this point, as children will see that the 0° to 180° line is a straight line. Once children are secure in the understanding that both a half turn and a straight line are equal to 180°, they move on to working out unknown angles on a straight line. The whole (180°) subtract each part; or add the parts first, then subtract from the whole. Ask: What strategies can you use to work out missing angles? Do you need to add or subtract to find the unknown angle? Why? If there is more than one missing angle but they are equal, how can division help you to work them out Answer sheet attached

This bundle includes decimal reasoning worksheets targeted at year 4. It includes different levels of abilities.

Use all four operations to solve problems involving measure [for example, length, mass, volume, money] using decimal notation, including scaling. The sheets increase in challenge. The first sheet is aimed at those working towards age expected. Children solve word problems involving subtracting and adding numbers with up to two decimal places; no exchanges. They solve word problems involving 2-, 3- and 4-times table and dividing by 10. The second sheet is aimed at those working at age expected. Children solve word problems involving subtracting and adding numbers with up to two decimal places; with up to two exchanges. They solve word problems involving all 12- times table and dividing by 100. The third sheet is aimed at those working at greater depth. Children solve multiple step word problems with up to two decimal places; with multiple exchanges. They solve word problems involving scaling and any multiple included.
