# Active mathematics exercise for 1 – 4 primary

Aball1 exercise booklet in mathematics for primary school! The tasks in the booklet are tailored to each grade’s curriculum, but can also be used independently in any grade for the repetition of skills. The 50 coloured balls are great for learning both estimating amounts and counting. On the balls, the numbers 1-9 are repeated five times. In addition, three balls are numbered 0, and there are two wildcard balls. The numbered balls provide plenty of practical learning opportunities, and can be used for different methods of calculation such as addition, subtraction, multiplication and division. Used together with the cones that are also included, the balls can also be used to create an understanding of fractions, time and measurement.

**Exercises tailored to the curriculum and the natural progress through the math coursework.****Easy to find exercises that bring physical activity and social learning into teaching.****Practice sorting, numbers, symmetry, addition and subtraction, multiplication, division, time, geometry, fractions and more.**

Below you will find some examples on Aball1 math exercises:

## Picking berries

Split into two teams.

Let all the balls out in the middle of the room.

One team is to pick blueberries (blue balls) and the other team picks strawberries (red balls).

Each team assigns one person the task of picking berries. The other team members form a big basket by joining hands. The big basket has to follow the picker, so that it is easy to pick and place the berries in the basket as quickly as possible.

Each team collects as many berries as possible, until all the berries are gone. The first team to return to the starting point is the winner.

Sorting

Among the blueberries there are some who are not completely ripe. They are marked with the number 5. Can you sort these out? Among the strawberries there are some which are really sour and they have the number 4. Can you sort these out?

## Magic Triangle

Split into three to five teams (max six persons per team).

Each team should have 6 cones set up in a triangle.

Exercise 1 – Relay

The teams run a relay to collect a ball with the number 1, then the number 2, up to 6. The balls are placed in correct order from 1 – 6, regardless of where in the triangle you start. First team to finish, wins.

Exercise 2

Place the numbered balls in the triangle, so that the sum of each side in the triangle is the same. The team that finds the most solutions wins. If two of the teams find all the solutions, the team that finishes first is the winner.

In how many ways can this be accomplished? How many different sums can you find?

Solutions

There are four possible solutions:

1) Place the lowest numbers in the corners (side sum 9)

2) Place the highest numbers in the corners (side sum 12)

3) Place the even numbers in the corners (side sum 11)

4) Place the odd numbers in the corners (side sum 10)

## Find the coin

Split into 4 teams.

Give the green cones and blue balls to two teams.

The other teams get the red balls and yellow cones. Two and two teams compete against each other. The teams place their cones in a 5 by 5 square. Mark the vertical lines of the squares with the balls A – E (square 1) and F – J (square 2) and the horizontal lines with the balls 1 – 5.

The students turn away, and the teacher hides a coin under a cone in each square. To find the coin, the teams alternate in giving coordinates to the cone they want examined, and the other team checks if the coin is there. If the coin is not under that cone, the team that gave the coordinates has to run one lap around the cones. It is important to remember which coordinates have been checked. The team that finds the coin wins.

## Multiple the answers

Split into four teams.

Each team starts in a corner of the room. The balls are spread out on the floor and the teacher stands in the middle.

The teacher calls out a multiplication question and the students have to collect the ball (or balls) that answers the question correctly. Example: 5 x 5 = ball number 2 and ball number 5.

The team has to hold hands in a circle when they go searching for the balls. The first team to find the balls and show the correct answer to the teacher, earns a cone. The first team to collect five cones is the winner.
