Mental Maths Activities – ideas from www.teachingideas.co.uk

 

• D’OH!!

I find it best played 2v2 to encourage co-operation and joint decision making. The players have one standard die and they roll to decide who goes first. Players then roll the dice as many times as they like and keep a running total BUT if they throw a number 1 they lose their current score and record zero (which can be easily turned in to a Homer’s face). This is called getting a D’OH!. Players can hold their current score by passing on the die to their opponents. An advanced version can be played with two dice and the two dice are then multiplied.

This is a great activity for quick addition and also introduces children to probability i.e. “When is it a good time to hold your score and pass the dice on?”

Players can have 5 turns each or continue for a certain duration.

• Who wants to be a Mathematician?

The class are told of the game based on the ‘Who Wants to be a Millionaire?’ TV programme.

All the children sit at their tables and the teacher selects a child to play the game by having a ‘fastest brain first’ Maths question. The child who gives the correct answer quickest comes to the front of the class to play.

When in the hot seat, the child has to answer three (or more) questions based on the learning objectives. These questions need to be answered as quickly as possible and only the first answer can be accepted. At the same time the rest of the class are told to think of the answer as well as, if the contestant gets it wrong you will be picking another player who has the right answer to sit in the hot seat.

Whilst in the chair the contestant gets two ‘lifelines’ to help him/her. These are ‘ask the audience’ in which the majority of right answers from the rest of the class could influence the answer, or ‘phone a friend’ where the contestant is allowed to ask one of his/her class friends to help them.

This activity is a great oral/mental starter but could be used as part of the main teaching activity.

 

 

• Jeopardy!

Pass out cards with numbers and colours on them to students. There are two teams, red and green. Call a number, and the two students with that number go up to the board. Ask a mathematical question, and have the students answer it. Do their ‘working out’ on the board.

When the first student’s done, have them ring a bell. The first student to ring the bell, check their work. If they get it wrong, go to the other student, but if they get it right, give them 1 point.

At the end of the game, tally up all the points, and the team with the most points wins.

 

• What’s my number?

Write the numbers from 1 to 20 up on the board and think of a number.  The children have to guess what your number is by adding two numbers together or taking two numbers away.  The children love it and the numbers also act as a number line.

Differentiation:

– Children who operate at an lower level can contribute through asking other relevant questions, e.g. is it less than / more than etc.

– For older / more able children, you can make the number line bigger (up to 30, 40 etc.)

 

• The Price is right!

The teacher chooses 2 children to stand in front of the board facing the class. The teacher writes a number betwen 1-100 on the board (both children should not be able to see it).

Then they take turns in guessing the number, after each guess the class must respond either ‘higher’ or ‘lower’. The game continues until one person guesses the correct number.

NOTE: Another way you could play this game is to get the two children who are standing at the front of the class to ask the rest of the class questions for them to be able to guess the number. For instance they could ask, is the number higher then 30? is it a odd number? is it between 20 – 50? is it a multiple of 10? etc. Children should only answer yes or no to the questions.

 

• Twister Maths

Make a mat from 20 A4 pages(or foam number squares or old Twister Game mats) joined together with the numbers 1-20 clearly written on them (I placed them in 4 rows of 5).

The children are then told instructions such as ” Put your left foot on the answer of 3 add 5″ and so on just like the game Twister!

Repeat until the child has 2 feet and hands on the numbers. I got the rest of the class to do “Thumbs up and thumbs down” if the child’s answers were correct (Also helps children learn their right from their left!).

 

• Number of the Week / Day

I use this mental maths activity with children aged 7 – 11. Choose a number of the week, which should be written on the board and can be referred to during numeracy lessons during the week. (The number should be suitable for the age and ability of the children).

Laminate the task/operation cards (i.e Read the number, divide/multiply by ten, round to the nearest ten, reverse the number, write the number in words, half it, double it, how many hundreds / tens/ units?, find a quarter etc)

In turn children select a card. Whatever it says the children have to work out the answer. For example if the card says – divide by 4, the children all divide the number of the week by 4. If you have individual whiteboards, all of the children can take part at the same time. Alternatively the individual who picked the card can work out the answer.

 

• Ball / Beanbag in the box

Set up 2 teams at their desks. At the front of the class put a box and mark a line about 2-3 metres  away. Choose a member of team A to stand on the line. The child must throw a ball /beanbag into the box. Place an “easy” and a “hard” set of question cards face down on the table.

• If the child gets it in, his/her team chooses an ‘easy’ question. If they get it right they win a point for their team.
• BUT, if they missed the box, the other team choose a ‘hard’ question. If they get it right they win the point.

Continue taking turns until everybody had had a chance to throw.
