# Package 4 - Year 1 and 2 Mathematics - Maths explosion 7 feet follow up

This task offers your child the opportunity to measure length using uniform informal units.

Week 6 - Package 4 - Year 1 and 2 Mathematics - Maths explosion 7 feet follow up

## Things you need

### Ideal

• Cardboard

• Marker

• Activity sheet 1

• Pencil

## Why is this activity important?

• conduct mathematical investigations in their home

• measure lengths using uniform informal units (the cut out of their foot) by placing them end to end with no overlaps

• explore that when an item is longer, more units will be required to measure it.

## Before you start

Check that the video is working and the audio settings are correct for your child.

## What your child needs to know and do

This task encourages your child to conduct mathematical investigations at home where they will need to explore to find solutions. They need to place the foot cut out end to end to get an accurate measure.

## What to do next

View the MathXplosion 7 feet follow up video.

Help your child trace around their foot on cardboard or paper and have them cut it out. This will be the unit that they will use to measure around the home.

Help your child to measure their own height using their foot measure. Are they 7 feet (their own foot) tall?

• Can you find some things that are more than 7 of your feet tall? Write and draw your findings in Activity sheet 1.

• Can you find some things less than 7 of your feet tall? Write and draw your findings in Activity sheet 1.

### Activity too hard?

Make multiple feet so that they don’t have to keep the place of the unit and then move it up.

### Activity too easy?

Measure more things with their foot or and cut out a measure of your foot so that they can investigate what happens when the unit used to measure gets bigger.

• Why is it important to iterate (place them end to end with no gaps) the unit?

• How many of your feet do you think your bed will be? Why?

Measure the same item using different units from the feet of different members of your family.

## Activity sheet 1:

Trace around your foot and then cut it out:

Use your cut out to measure your height. Are you 7 feet tall?

Can you find some things that are more than 7 of your feet tall? Write and draw your findings.

Can you find some things that are less than 7 of your feet tall? Write and draw your findings.
