Fun Outdoor Maths: Counting and Shapes

Fun Outdoor Maths

This lesson is designed for Grade 1. Central thread: children can use outdoor objects to count, compare, and spot simple shapes in the world around them.

Our learning goal

I can count, compare, and find simple shapes outdoors.

What maths things can you spot outside?

Use this to activate prior knowledge. Expect words such as leaves, stones, numbers, shapes, circles, sticks, more, and counting.

Counting things outside

• Leaves, stones, sticks, and flowers can be counted

• We count one object at a time

• Each object gets one number word

• The last number tells how many there are

Emphasise one-to-one counting. Keep examples concrete and visible.

Numbers can match groups

A number shows the size of a group.

• 3 leaves means a group of three

• 5 stones means a group of five

• 8 sticks means a group of eight

• The numeral and the group should match

Link spoken number words to written numerals if helpful, but keep the main focus on matching quantity to number.

Making small groups

• Put objects into groups

• Count each group carefully

• Check that no object is missed

• Different objects can still be counted the same way

Useful bridge from collecting objects to later comparing groups.

Counting in order

Counting works best when numbers stay in order.

1, 2, 3, 4, 5 …

If we skip a number or count one object twice, the total will be wrong.

Model common mistakes briefly: skipped numbers and double counting.

When do we know how many objects there are?

A

After the last number

B

After the first number

C

After one object

D

After a guess

Checks the idea from counting slides that the last number said tells how many there are.

Counting carefully

We count one object at a time. Each object gets one number word. We say numbers in order so the total is right.

number

order

group

same

shape

more

The key taught words are one, number, and order.

Comparing groups

• Some groups have more

• Some groups have fewer

• Some groups have the same number

• We compare after we count

Use clear side-by-side examples such as 4 leaves and 6 stones.

More, fewer, same

When we know the numbers, we can compare them.

• 7 is more than 5

• 3 is fewer than 6

• 4 and 4 are the same

Keep language consistent: use more, fewer, same throughout.

Lining up objects

• Lining objects up helps us compare

• One row can be matched with another row

• If one row has extras, it has more

• If all objects match, the groups are the same

Introduce simple one-to-one matching as a comparison method without formal terminology.

Using number words to compare

We can describe groups clearly.

• 'The stick group has more.'

• 'The leaf group has fewer.'

• 'Both groups have the same number.'

This slide supports the literacy-maths link by giving pupils precise comparison language.

Which word fits 7 leaves and 7 stones?

A

More

B

Fewer

C

Same

D

Round

Uses comparison language from slides 6 to 9. 'Round' is a shape word distractor from the later topic.

Comparing groups

We compare groups after we count. If one row has extras, it has more. If all objects match, the groups are the same.

after

more

same

before

fewer

triangle

circle

Reinforces both ways of comparing: counting first and lining up objects.

Which comparison word feels easiest to use?

1

More

2

Fewer

3

Same

Shapes we can find outside

• A circle can look like a round stepping stone

• A square can look like a paving tile

• A rectangle can look like a bench seat

• A triangle can look like a roof shape

Use familiar outdoor examples from school grounds where possible.

Circle, square, rectangle, triangle

These are simple 2D shapes.

• A circle is round

• A square has 4 equal sides

• A rectangle has 4 sides

• A triangle has 3 sides

At Grade 1 level, keep definitions simple and visual rather than technical.

Shapes on real objects

• We can find shapes on signs, windows, and paths

• One object may show more than one shape

• Shapes in real life may be big or small

• Maths helps us notice them

Helpful moment to show that maths is part of the everyday environment.

Sorting by shape

We can sort outdoor objects by the shapes we see.

• round shapes together

• triangle shapes together

• square shapes together

• rectangle shapes together

Sorting prepares pupils to classify and justify simple choices.

Which shape has 3 sides?

A

Rectangle

B

Triangle

C

Circle

D

Square

Simple recall of the key shape property from slide 11.

Shapes outside

A circle is round. A square has 4 equal sides. We can sort outdoor objects by shape.

Echoes the exact shape language taught on slides 10 to 13.

What is one thing you learned today?

Look for one clear thing the pupil learned, such as counting in order, comparing with more/fewer/same, or finding shapes outside.

What helped you learn best today?

Encourage pupils to mention a helpful activity or idea, such as lining up objects, counting one at a time, or spotting shapes on real objects.
