Solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why
|Bubble Pop - Number Bonds||
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.
|Thinking of a Number||
Use inverse operations to work backwards and find a missing number.
|Balancing scales - convert between g and kg||
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.
|Balancing Scales g and kg||
Add weights to either pan until they are balanced. Can be used to teach addition, subtraction, partitioning, and mass, as well as developing an understanding of the equals sign.
|Balance scales - add, move or remove a weight||
Balance the scales by adding, moving or removing a weight. A great mental starter to develop addition and subtraction skills.
