# Activities

Programme of Study statements Activities
A B C D E
Add and subtract whole numbers with more than 4 digits, including using formal written methods (columnar addition and subtraction)
Add and subtract numbers mentally with increasingly large numbers
Use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy
Solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why

## Activity A – Two and Two

Challenging activity which requires finding the numbers which each letter stands for in an alphanumeric question

## Activity B- Reach 100

A challenging activity from Nrich requiring the children to place digits in a 2x2 grid so that the four 2-digit numbers made, total 100. Can they extend it to a 3x3 grid? What might their total be? What about a 4x4 grid? Can their reach a total that is a multiple of 1000?

‘Rounding’ and ‘Rounding Decimals’ are two spreadsheets from this wider set, produced by the National Strategies, and now hosted in the STEM Centre E-library. They allow a number of a given size to be generated and a level or accuract for the number to be rounded to. The rounded number can then be revealed. Teachers’ notes are also included.

## Activity D- Ordering the Problems

Children could be provided with a variety of one and two-step problems. They can be asked to estimate the answers to each, then order the problems according to their estimates.

## Activity E-CIMT Problems (pdf)

Pages 70 – 75 of this workbook contain a variety of multi-step problems

## Write the Problems

Children could be given written calculations such as 23 456 + 46 019. They could be asked to write an imaginative problem that would require this calculation. Can they extend their problem to make it a multi-step problem?

As a variation of this, give children a selection of cards. Some should contain word problems and others should contain the corresponding calculations. Children should match the problems to the appropriate calculation.

## Other problem solving opportunities

Wherever possible, try to link problems to cross-curricular topics, so that children get used to solving problems with a real-life context.

Display a ‘problem of the week’ in the classroom, with an opportunity for pupils to respond, perhaps by posting their answer into a box or container.
