Lesson Objective
To measure the capacity of containers
To measure the volume of containers
Steps to Success
1. Capacity
-
1 litre = 1,000 ml
-
What is half?
-
Count in hundreds
2. Volume
-
Count cubes
-
Calculate the area of the base
-
Multiply by height
-
Volume = L x W x H
-
Cross off zeros and add
-
Add vertically if needed
-
cm³
Notes
-
Ensure LA and LMA have practical experience of counting cubes to understand volume.
Starter (15 mins)
-
Check self assessment (PP65M.8.1-Slide 2)
Review prior learning (PP65M.8.1-Slide 3). Watch Scene 07.1 (PP65M.8.1-Slide 4) and look at measuring capacity in millilitres and litres (PP65M.8.1-Slides 5-7).
Talk Time (Pairs organised by ability)
Learners choose or are told which calculations to do. If finished, learn times table. Teacher or learners model answers, assessing learners if needed. (PP65M.8.1-Slides 8-9)
Go through workings and answers.
Main (20 mins)
Watch the final part of Scene 07.2 (PP65M.8.2-Slide 2). Discuss volume and the difference between capacity and volume. (PP65M.8.2-Slides 3-5)
Look at a problem and discuss how to find volume by counting and measuring in cm cubed leading to Volume=Length x Width x Height, repeat and add actions e.g. hold a hand out in front with a fist for volume, hand moves horizontal for length, cross hands for multiply, hand goes forward for width and then vertical for height. (PP65M.8.2-Slides 6-8). Using a multiplication grid to support, look at a number of problems increasing in complexity- multiplying by tens and using vertical addition. (PP65M.8.2-Slides 9-14)
Talk Time (Pairs)
Learners choose or are told which calculations to do. LA to use cubes to create a cube and then count. Learners invent own if finished. Teacher or learners model answers, assessing learners if needed. (PP65M.8.2-Slides 15-16)
Introduce the steps to success and activities for Group B, C, D & E. Highlight any tricky questions, clues and explain any extra work/extension if they finish. (PP65M.8.2-Slides 17-21)
Groups (20 mins)
LA (Group A or B)
Read simple scales to measure capacity (PP65M.8.1-Slides 10-11 & PC65M.8.1) or measure volume by counting cubes (PC65M.8.2).
Ext – Find the volume of cuboids (PC65M.8.3) & PC65M.4.1)
LMA (Group C)
Find the volume of cuboids using a multiplication grid to support. (PC65M.8.3 & PC65M.4.1).
Ext – Find the volume including multiples of ten.(PC65M.8.4).
MA (Group D)
Find the volume of cuboids including multiples of ten (PC65M.8.4).
Ext – Find the volume including multiples of ten and vertical addition (PC65M.8.5).
HA (Group E)
Find the volume of cuboids including multiples of ten and vertical addition (PC65M.8.5 Section A).
Ext – PC65M.8.5 Section B & C with support

Focus: |
 |
| |
Use of animation, beaker images, scales, times table grid, cuboids, cubes, colours and animations in vizualising area. |
 |
Repetition of “Volume=Length x Width x Height”. Discussion in talk time. |
 |
Add actions such as holding a hand out in front with a fist for volume, hand moving horizontal for length, crossing hands for multiply, hand going forward for width and then vertical for height. Talk time for learners to have a go. |
