# Mental maths

A resource that focuses on mental math skills or instant recall of facts such as times tables.

Major update Use compensation strategies to speed up mental addition when adding on numbers such as 19 or 39. A step by step work sheet: the pre-skills check is followed by more than 60 questions (including 'Stretch' tasks). Concludes with two new pages of Functional Skills exam style problems that can be used independently of pages 1-3. Exam style questions are based on a bike shop and a children's nursery.

In addition, an answer and detailed mapping sheet is now available to contributors.

Practise using reordering strategies with these extra E2 (E1 questions are in a separate Wordwall activity) questions for our recently updated E1-E2 Mental addition strategies (reordering) PDF worksheet (Maggie Harnew, 2005, updated Feb 2022). Match the correct answer to each addition problem. (Reordering involves adding up large numbers first and/or looking for pairs of numbers that add up to 10, 20, 30, etc.). **Can be used independently of the original resource.**

An introductory PPT based task to find the value of the three words in ‘Happy New Year’, given certain values for each letter. This is followed up by a set of question cards on calculations with the letters of Happy New Year and an algebra worksheet with the same given values, using BODMAS.

A set of cards where learners have to find fractions of money. I use this as a paired game where the learners share the cards between them, then both turn over one cardeach. They work out how much their card is worth then the “winner” or person whose card is worth more keeps both cards. Play continues until 1 player has all the cards.

A lovely selection of quick generic and contextualised whole number and decimal problems to improve mental arithmetic skills.

A great way to start a class – provides mental maths practice for E2-E3 but also suitable for higher level learners who can try it out with with large numbers and discuss how it works!

A super, quick-to-prepare paired game (all you need is paper, pencil and two dice) that is easily differentiated for any E1-E3 group. Example games include addition, subtraction and times tables.

A rather nifty Word document template where learners can move the digits to the right or left to see the changes in place value when multiplying or dividing decimals by 10, 100 and 1000.
