## Introduction to capacity and volume

• Year group: Year 1
• Term: Spring
• Topic: Length, weight and volume
• Duration: 1 weeks
• Keystage: KS1
• Age Range: 5 to 6 yrs
• Unit can be taught out of sequence: Y
• Week Range: 11

In this chapter, pupils are exposed to the concepts of capacity and volume as measurements through real-life, relatable examples, which will help them to build the foundations of their understanding.

Pupils handle and fill a variety of objects, such as jars, bottles, jugs and cups, and compare, describe and solve practical problems involving capacity and volume. They should use language such as “full”, “empty”, “more than” and “less than”, and link to their work on fractions by using language such as “half”, “half-full” and “quarter”.

Additionally, pupils measure and record capacity and volume using non-standard measuring equipment, such as cups.

## Resources for this topic

### White Rose Maths

#### Mass and capacity

Two worksheets for an introduction to mass and capacity.

#### Capacity, volume and mass

### Mathematics Mastery

#### Introduction to capacity and volume

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of capacity and volume.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Like what you see? Mathematics Mastery is a professional development programme for teachers with a mission to transform mathematics education in the UK.

This task is just a taster of the complete classroom resources we offer. We also provide in-depth development training, online CPD, specialist support and assessment tools.

We believe all elements of our programme are vital in creating lasting change – enabling every child to enjoy and succeed in mathematics.

### Resources shared by teachers

#### Year 1 – Spring – Week 11 – Measurement: Weight & Volume

This is pack 2 of 2 for the fourth block, Year 1 Measurement: Weight & Volume. It supports small steps, Introduce capacity,
Measure capacity and Compare capacity. It contains ideas and resources that support a mastery and CPA approach, encouraging learning through practical activities, engagement with pictorial and abstract resources, and reasoning and problem solving within the context of measuring. I hope you find it useful.

#### Measures

Conversion of units

#### Capacity

Estimating volume - to start having a think about capacity. Jug measuring - For top ability group with support, thinking about measuring in ml and counting in 100s and 1000s. Challenging - good scaffold for relevant vocab use. Measuring out into cups - Used for my BA group to do with support. Some time will be needed to collect resources but if you put a note in the staffroom or ask parents these things can be collected faster (then keep them for next time) As said on sheet adding food colouring and sequins makes it that bit more exciting! Thank you :)

#### Capacity: Magic Potions + empty measuring jug

Following our World Book Day, here is a lesson planned for a P3 class. Opportunity was endless as children were keen to make and write their own potions. Adapted the potion idea from a fellow tes member, but added my own names/instructions/worksheet plus an additional empty measuring jug for practice with scale. There is also an early years version using different-sized cups instead of measuring in ml.

#### Length, weight and capacity

A summary of standard units used for measuring with questions for the children to discuss. Please leave a comment if you have time!
