Materials:

• Tens frames
• Unifix
• 10 sided dice

Students work in groups of 4-5 and start with 10 unifix on each of their tens frame. They each roll the dice and take that many away from their own tens frame, saying the equation e.g. 10 subtract or take away 2 is 8. Once each student has taken away a number, they need to look at each other’s board. Ask students to say their own number aloud in order from smallest to highest, highest to smallest and discuss numbers that are in the middle and what is the difference between highest and lowest etc. This activity encourages students to look at their own number in relation to their group members and think about the place value of each number. It can be reversed to include addition.

## Movie World Project

## Rock Paper Scissors

### Posted by Perri Wilkinson | Posted in Addition, Division, Factors, Four Operations, Multiplication, Number, Place Value, Prime Numbers, Rounding, Subtraction | Posted on August 28, 2017

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

## Odd and Even

### Posted by Perri Wilkinson | Posted in Addition, Division, Four Operations, Multiplication, Place Value, Subtraction | Posted on August 28, 2017

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.

## Alien Invaders 2.0

### Posted by Perri Wilkinson | Posted in Decimals, Division, Multiplication, Place Value, Subtraction | Posted on August 28, 2017

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.

This is a calculator warm up activity for place value, addition and subtraction.

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 by subtracting the numbers one at a time.

For example:

• A student’s number is 5271. They must first get rid of the 1 by subtracting 1. Leaving 5270.
• They must then get rid of the 2 by subtracting 200. Leaving 5070.
• Next they need to get rid of the 5 by subtracting 5000. Leaving 70.
• The last step is to subtract 70. Leaving 0

## Please may I have?

This is a great warm up activity  for place value, addition and subtraction.

Each student has a calculator and must enter a 4 digit number (with each digit being a different number). The students then take it in turn asking each other for a number. If the student has that number, they must subtract it from their number and the student asking must add it to theirs. They continue this until either one person has a 5 digit number (making them the winner) or one person has a 3 digit number (making them the loser).

For example: Student A starts with 5831 and Student B asks for an 8. Student A must subtract 800 from his number using the calculator, leaving 5031, and Student B adds 800 to their number.

Support: starting with a 3 digit number, recording their working out

Extension: higher digits, decimals, explaining their strategy to win

## Race to 1000

### Posted by mrslonsdale | Posted in Addition, Subtraction | Posted on May 21, 2017

1. Each player draws 6 cards
2. Using two three digit numbers create an addition problem. Your goal is to get the sum as close to 1000 as possible.
3. The player whose addition number is closest to 1000 wins the round.
4. Play 6 rounds, whoever wins the most rounds wins the game!

## Four Operations Games

### Posted by Perri Wilkinson | Posted in Addition, Division, Four Operations, Multiplication, Subtraction | Posted on September 14, 2016

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.

## Harry Potter Challenge

### Posted by Perri Wilkinson | Posted in Addition, Division, Four Operations, Multiplication, Number, Subtraction | Posted on September 7, 2016

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.
