Warm up activity for number and place value that can be adapted to many concepts.

Students say rock paper scissors and then hold out fingers. They must then perform an operation and say the answer to win.

Variations:

- add the number of fingers
- find the difference between the number of fingers
- multiply the number of fingers
- identify odd or even numbers
- perform one of the operations above and then identify if it is odd or even
- perform one of the operations above and then identify if it is a composite or prime number
- perform one of the operations above and then identify multiples or factors of that number
- multiply the numbers and round to the nearest 10

The aim of this warm up game is for students to try and work out a way to make the final number either odd or even.

Students need a calculator and cards with the digits 0-9 on them.

Students place the cards face up on the table and choose who will be odd and even. Once they have decided who starts, they take it in turn flipping a card over. The first card is the starting number and they enter it on the calculator. That card is then turned over. The next player chooses a remaining card and an operation. They must do that operation with the chosen number on the calculator and continue until there are no cards left. The final number determines the winner, either odd or even.

One rule is that neither player can divide or multiply by 0.

This is a memory style card game with a twist. Players make equations from the three cards that they flip over.

2-4 players

The cards are all placed in rows face down.

Players take turns to flip over three cards and attempt to make an equation using the three cards. The equation can be an addition, subtraction, multiplication or division, e.g. 3+3=6, 8-5=3, 2×1=2, 10÷2=5.

If the player can make an equation they keep the cards. If they can’t make an equation the cards are flipped back over in the same place.

Continue playing until the cards are all gone. The winner is the player who has the most cards.

Students need:

- iPad with QR code scanner app.
- QR code game board

Students can scan the QR codes on an iPad and play any of the 6 online Maths games. They can choose the operation they wish to practise and the level of difficulty.

This is a great activity for students to practice the mental maths strategies.

Students are to sit in a circle with 2 students standing in the middle back to back. The students take 3 steps away from each other. The teacher needs to call out a Maths problem for the students to solve in their heads. The first student to solve the problem can turn around and zap the other student with their wand. They can then reveal their answer. If they were wrong the other person wins the round. The person who is out can switch with someone in the circle.

This is a great warm up game that encourages students to use their mental maths. It has been taken out of the *Maths on the Go Book 2.*

You begin with a group of students standing. Tell the students a number. e.g. Year 2s you could give them 20, 3s and 4s 50 and 5s and 6s 100.

You must then give the students a problem and they have to solve it in their heads. You may like to give them a set time frame e.g. 10 seconds. They must then figure out if their answer is smaller or larger than their given number. If their answer is larger than the given number, they must put their hands on their heads. If it smaller, their hands will go on their hips. Tell students to not put their hands on their heads or hips until the time is up so there aren’t any students who copy. You can then go around asking students to explain how they got their answer. If a student has their hands in the wrong place or can’t explain their thinking, they can sit down.

This is a multiplication warm up game that can be used for students working at various levels. The kids love it and it really does work for reinforcing times tables.

- You need a deck of playing cards.
- Students play in pairs, threes if needed.
- Depending on the students level you can either instruct them to remove the picture cards or assign each picture card a number i.e. Jack and Queen are 11 and King is 12.
- Students then get given a Magic Number (decided by the teacher).
- The students place all the cards in a pile and begin flipping one card over at a time.
- Students need to multiply the card by their magic number and call out the answer.
- The first player to do this gets to keep the card. The student with the most cards at the end wins.

This is a Maths warm up game that can be used to practise both Place Value and Addition skills.

Teachers set a target on the board and in like ability pairs students use a calculator to try and add numbers together to hit the target. This can be used to practise the other operations as well.

For example, the target is 25

Students 1 puts 4 into the calculator

Student 2 needs to figure out what they need to add to 4 to get 25. In this case, they add 21.

Variation: students can play it where they have to add multiple numbers together to hit the target.

For example, if the target is 71.

Student 1 puts 12 into the calculator

Student 2 adds 9 to 12 which equals 21 and so on and so forth.

Students create questions based around themselves with numerical answers, e.g. age, house number, number of siblings, number of letters in their first name, shoe size.. (the list is endless). Once students have the answers, they have to create equations to be worked out to get to their answer, e.g ‘My Age’ Answer=12, Equation could be 2×6= 10+2= or even more advanced using BODMAS, decimals, fractions etc.

Once students have created the equations and answers, they present these on a poster with the equation displayed on a piece of paper or a post it note that can be opened up to display the answer underneath.
