Treasure Hunts

An old favourite. Pupils work out the calculations then colour in the corresponding square on the treasure map, the single remaining square is where the treaure is buried. A great way to make pupils do 50 sums! To follow up, ask pupils to create thier own treasure hunts for you to copy and friends to complete. Question sheets on pages 1, 2, 3. An example of pupils work on page 4. Answers on pages 5, 6, 7.

Mental Arithmetic Practice

An excel file for generating endless mental arithmetic practice. Press F9 to recalculate the questions. Try our Ks3 Mental Tests mini-site also.

Numeracy Checkup

Sets of questions on various basic numeracy methods. Includes fractions of, percentages of, simplifying linear algebraic expressions, solving simple equations, decimal addition plus several more. 'How to...' document for students to learn independently.

Approximation

Two similar sets of questions for pupils to practise calculations after finding upper and lower bounds. Answers to come soon.

Estimation

A run through of rounding 'to the nearest', 'to decimal places' and 'to significant figures' with a dash of SMSC thrown in.

Using a Calculator

Prompts for essentials to learn in order to ge the most from our calculator. Based on using the Casio FX83.

I Can Calc

Calculations to check if you really know how to use your calculator.

Pupils use knowledge of times tables to complete the missing spaces on the tables. Note that digits 2-9 are used only once along top row & LHS column.

BISMAS in Russian

Pupils first translate the russian words into numbers and, having done so, do the Russian BIDMAS calculations. Just simple calculations at first and then more complex ones. Answers are easier to mark if given in figures, do as russian words as an extension. You'll need all of these files Russian Numbers , Cryllic and Russian Numbers 2. Don't worry if your Russian isn't good - answers are included!

3 Digit Random Number Generator & Countdown Clock!

Does what it says! You can click between two screens, with the number big or small, to provide room to scribble things down on your IWB.

Revises types of number, factors etc & gets all pupils engaged. Can be changed very easily to aid differentiation (e.g. 'multiple of 25' can become 'multiple of 27', can be changed to a 4x4 grid easily...).

Times Table Challenge

Pupils race against the clock to complete 10 multiplications

Non Calculator Number Questions

Worksheet of various number questions. Includes answers.
