Solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why
Using a Calculator - Finding Change
Answer a variety of 2 step word problems using a calculator. Whatever is input into the calculator is then recorded and displayed, so children can see all the steps that have been taken. This makes it a great tool for demonstrating calculator skills on a whiteboard. It can also be really useful for children to practice independently, as they can trace and correct any mistakes they make.
The scale is loaded with between 1 and 4 weights. The user then has to balance the scales, converting between g and kg in the process. There is a great deal of control over the level.
A great starter to explore addition, subtraction / difference and partitioning as well as the relationship between grams and kilog More…rams. Levels include converting whole kg to g (and vice versa), converting fractions of kg (eg 1/4kg = 250g) and weights in kg to 1 and 2 decimal places.
An excellent tool for reinforcing an understanding of the role of the equals sign. Choose one objective, or many. You can choose all the objectives for a single year group (or multiple year groups). You can also choose to balance between different types of calculations (eg addition and multiplication).
A great way to practise number bonds and mental addition. Levels include: number bonds to 10, 20, 50 and 100 as well as addition pairs with a total of up to 20, 50 or 100. Look at the target at the top of the screen and then aim your bubble to make that target.
As a teacher I know how important it is that children know their number bonds (pairs of numbers that add up to 10, 20, 50 or 100), and can add quickly mentally. Repetition is essential in learning number bonds. This game is designed to make the process fun.
Children have to aim their bubble to make a given sum. As they progress the levels get harder; they have less time, or less bubbles to shoot. Each correct answer is accompanied by an image to reinforce the number bond they have found.
This game is available on iPad, iPod and iPhone, as well as on android phones and tablets.
A fun game to practise mental addition skills. The game was designed to cover all the mental addition objectives in the new math curriculum. You can choose one objective, or choose all the objectives for a year group.
This game, together with all the other crystal crash games, is available as a single iPad or Android app.
