It’s really useful to stick on the wall by your child’s desk as a reminder on how to covert length (e.g. mm, cm and metres), mass (e.g. grams and kilograms) and volume (e.g. litres and ml).

Here are three Year 4 geometry worksheets covering symmetry, perimeter and area. Note that the first two would also be suitable for Year 3:

Year 4 Geometry – Worksheet 1 e.g. Symmetry

Year 4 Geometry – Worksheet 2 e.g. Perimeter

Year 4 Geometry – Worksheet 3 e.g. Area

One worksheet which uses multiplication wheels which is generally easier and more fun for children to fill in that “square” times tables.

Also included here are three Number Machine workouts which use three steps of maths targeted at Year 3, for example an addition, a multiplication and another addition. These are great fun and introduce children to working out multiple-step answers:

Year 3 Multiplication Wheels

Year 3 Number Machines – Worksheet 1 – e.g. uses addition, subtraction and multiplication with an input number and an output number

Year 3 Number Machines – Worksheet 2 – e.g. uses addition, subtraction and multiplication with an input number and an output number

Year 3 Number Machines – Worksheet 3 – e.g. uses addition, subtraction and multiplication with an input number and an output number

Here are three worksheets which use a number-line and thermometer to help introduce and secure the basics of negative numbers:

Year 3 Negative Numbers – Worksheet 1 e.g. 1 – 2 = -1

Year 3 Negative Numbers – Worksheet 1 e.g. 1 – 6 = -5

Year 3 Negative Numbers – Worksheet 3 e.g. “What will the temperature be if it warms by two degrees?”

Remember that the factors of an odd number are all odd.

For example the factors of 15 are: 1, 3, 5 and 15.

If we look at a bigger number like 2,469 the factors are: 1, 3, 823, 2469.

And just to prove the point, for a huge number like 24,648,021 the factors are: 1, 3, 9, 53, 159, 477, 51673, 155019, 465057, 2738669, 8216007, 24648021.

Phew!

The average ten year old child will walk at about 4km per hour.

With this knowledge a Ninja Maths Master should be able to work out that 6km is one and a half times 4km, so the time taken will be one and a half times one hour which is one and a half hours!

Ask how long it would take to walk 40km. The answer will not be ten hours. Why?

Here are six worksheets which require multiplication (times tables) and addition to solve questions such as “If an apple cost 14p, how much change will you get from the shopkeeper if you buy five apples with a £5 note?”
