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.

**Activity: **10 Cup Bowling

**Equipment:**

- 10 cups per group
- 10 balls
- Masking tape to create lanes
- 1 x Scoring paper/mini whiteboards and markers per group

This activity is to be completed in small groups of up to 6 players. Students will begin to explore basic subtraction facts from 10 by taking it in turns to bowl down as many cups as possible in one turn. Students will practise verbalising the amount knocked over using number sentences e.g. “Ten take three is seven.” This will provide the next student in line with the player’s score for that turn, which they will record on the score sheet. After all students in the group have had a turn, the winner is the student that has the ‘lowest’ score.

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)

**Car Park Dominoes.**

(prep)

**Materials: **

Template

Set of dominoes.

I**nstructions**: The aim is to fill up your carpark spaces by adding the two numbers on the domino together and putting it into the space with correct answer.

An extra challenge for students could be that they need to write their own numbers in the spaces.

This activity could also be done for subtraction and multiplication with the blank template provided.

This is an opened ended activity, allowing students to use the four operations. Students read the problem and record all the ways that they try to solve it.

Problem:

Sally was making numbers on her calculator but the keys for the number 6 and the number 7 were broken.

Sally wanted to display the number 467 in the calculator’s window.

How many ways can you make 467 on the calculator if the 6 and the 7 keys are broken?

Example of a solution:

400 + 30 + 30 + 4 + 3 = 467

Four Operation Games – QR Codes

Students need an iPad or iPod with the QR code scanner application.

Students can scan the QR codes and it takes them to a game that involves one of the four operations.

**Get out of my house**

By Michael Ymer

Focus – addition and subtraction facts to 20.

Suitable for Prep-Year 6

**You will need:**

- Game board with the numbers 0-20 displayed in a grid.
- Dice: 6 sided dot dice and 10 sided dice.

Each student has 7 counters of the same colour. Their partner has a different colour but also needs seven.

Students take turns in rolling the two dice. They may add or subtract the numbers to make an answer (depending on what they can do). One of their seven counters is placed on the number. The objective is to get all 7 counters on the game board before the other player. If a student lands on top of a number that has their partner’s counter on it they take their place and send their counter back to their partner. Students can have more than 1 counter of their own on the same number but if their opponent lands on that number all counters are sent back.

**Differentiation:**

1. Add or subtract numbers to make an answer with the two dice.

2. Use ten sided dice.

3. Use three dice.

4. Allow any operations – division, multiplication, addition or subtraction.

5. Simplify the game by using a 0-12 game board and only two six sided dice.

This is a great, quick activity to get the learners into the mood for maths! You will need to play the song “**The Final Countdown**” by Europe to set the tone. (Air guitaring is acceptable and encouraged!) Learners work in their maths books, dating in the margin to allow teachers to track improvement over time. The teacher gives the class a starting point and tell them what they are counting by. (For example, starting at 0, count forward by 10s.) Students then have a set time (I usually give 2 minutes) to count as far as they can. At the end of the time they all stand up, start at the beginning point and count aloud together. When learners get to their finishing point they sit down.

To mix it up you can start at different points, count forwards or backwards and change the number you are counting by. You could even get the learners counting using fractions or decimals!

Tools – deck of cards (remove coloured cards)

2 or more students

On student begins by calling “multiply”, then deals two cards face up (eg. 5 and 7). Once the second card is dealt the first student to multiply the two numbers correctly collects the two cards dealt.

The student with the most cards (because he/she has answered correctly) wins the game and becomes the dealer.

Depending on the level of students’ ability you can change from multiplation to addition or subtraction etc.

A dealer can deal more than two cards – eg. the dealer calls adding 3 cards (eg. a 5, 7 and 2 are dealt), the first student to call “Snap!”and can answer correctly, collects the cards. The dealer can alternate by calling out, multiply, add, subtract etc.).

Students can use a thinkboard to develop Subtraction strategies. Cards or dice can be used to create an equation appropriate for the student which is written in the centre. Students then use four different strategies to solve the equation. These are recorded in the four outside sections of the thinkboard.
