Students pick a division equation out of the bag/box and they will make it with counters and draw a picture.

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 warm up activity involving calculators for place value, decimals, subtraction multiplication and division.

Students begin by entering a 4 digit number into their calculator. These 4 digits are aliens coming down to earth. The students’ mission is to shoot them down in ascending order but this can only by subtracting the ones. Students will have to change the value of each digit by either multiplying or dividing the number by 10, 100 or 1000.

For example:

- A student starts with the number 5236.
- The first number they have to shoot down is the 2. Therefore, they must divide their number by 100 so that the 2 is in the ones column, e.g. 52.36. Then they can subtract 2, leaving 50.36.
- Next they must shoot down the 3. First the must multiply their number by 10 making 503.6 and then they can subtract 3, leaving 500.6
- Students continue until all digits are gone.

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.

Played in groups of 3-4

Students place KABAM! cards face down on the table. Students take it in turn to flip over a card and solve the division problem. If the students gets the answer correct they can keep the card, if they are incorrect they can place it back in the table. If a student picks up a KABAM! card they must put all their cards back down on the table and start again.

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.

**Materials:** Coloured pencils, plain paper and counters.

**Task details:** This activity can also be linked to the text ‘When the doorbell rang’. Students will draw a cookie jar in the middle of their page and place cookies (counters) within the drawn jar. Students will then draw a picture of themselves and a friend. They will then share out the cookies evenly by moving the counters one at a time. Once the cookies have been shared out they will draw and write the amount of cookies each person gets.

**Skills: **Counting, sharing and grouping.

**Extension:** Have more people to share the cookies between such as, the member of the students’ family.

Include different coloured counters (different flavoured cookies) which will need to be grouped before being shared.

Students design and create a game board in the style of their choice.

Students create question cards using the four operations. (i.e 8 addition equations, 8 subtraction, 8 multiplication and 8 division) There can be a mixture of number sentences and worded problems.

Each process is written on a different colour card.

Game boards include sections where players pick up cards as well as general game instructions. (i.e move back 2 spaces. Roll a 5 to move again)

The game board can also be used for:

- Measurement (to measure how long your journey is)
- Money (collecting and taking away money amounts along the way)
