## Unit 1 Measure using a uniform unit (suggested as 3 days)

### Objectives

Measure using a uniform unit
Unit 1: ID# 1459

National Curriculum
Meas (i) (ii)

Hamilton Objectives
17. Compare objects according to height and length using appropriate mathematical language.
18. Count uniform non-standard units to measure length and height.

### Planning and Activities

Day 1 Teaching
Show children a chair and a cube. How many cubes high do they think the chair will be? Estimate then measure the chair height in cubes (10s and 1s). Repeat, to measure the height of other objects in cubes.
Group Activities
-- Measure classroom objects with cubes.
-- Estimate and measure using a (30cm) ruler.

Day 2 Teaching
Use a 20-bead string to measure a child’s hand span in beads. Measure other hand spans, estimating the length first. Then work in pairs to estimate and measure each other’s foot lengths in beads.
Group Activities
-- Make a play dough worm family within a certain length.
-- Find objects longer/shorter than 20 beads.

Day 3 Teaching
Take children to the hall. Pass metre sticks around. Ask children to feel their length. These are one metre long. Explain that these are a standard unit. Measure the length of the hall in metres by laying sticks along one side. Repeat to measure its width.
Group Activities
Use the ‘Make a stick’ in-depth problem-solving investigation below as today’s group activity.
Or, use this activity:
-- Find objects longer/shorter than a metre stick.

## Unit 2 Compare and measure weights (suggested as 3 days)

### Objectives

Compare and measure weights
Unit 2: ID# 1471

National Curriculum
Meas (i) (ii)

Hamilton Objectives
17. Compare objects according to weight using appropriate mathematical language.
18. Count uniform non-standard to measure weight.

### Planning and Activities

Day 1 Teaching
In advance, make a spring scale (see instructions below plan). Pass round a handful of cotton wool, a potato and a large pebble. Children say which they think will weigh more. Which is heavier? Use the scale to compare their weights. Which pulls the elastic band the furthest?
Group Activities
-- Weigh fruit by holding, then order.
-- Use a spring balance to weigh fruit, and then order.

Day 2 Teaching
Use a bucket balance or balance scales. Use a large potato and a large pebble. Put the potato in one side and the pebble in the other side. Explain that the heavier object makes the balance go down on that side. It is like a see-saw. Let children ‘be a balance’, like a see-saw, with arms outstretched.
Group Activities
-- Compare objects to the weight of a book and find objects that are heavier and lighter.

Day 3 Teaching
Use a balance scale. Put an apple on one side then put marbles on the other until the scale balances. Count the marbles. Repeat to weigh a book/ other objects in marbles/ blocks.
Group Activities
Use the in-depth problem-solving investigation ‘Presents’ from NRICH as today’s group activity.
Or, use this activity:
-- Use bricks to estimate and weigh different pieces of fruit/ vegetables.

### You Will Need

• Spring scale, cotton wool and potato
• Large pebble/stone
• Two spring balance
• Range of fruit and vegetables and sticky notes
• ‘Comparing weights’ sheet (see resources)
• Tins of similar weight
• Balance scales, books and marbles
• ‘Heavier and lighter’ sheet (see resources)
• Other items to weigh
• Wooden bricks or compare bears

### Mental/Oral Maths Starters

### Worksheets

Day 1
Recognise which of two items would weigh the most,

Day 2

### Mastery: Reasoning and Problem-Solving

• Which is heavier:
(i) A potato or a pebble?
(ii) A book or a shoe?
(iii) A soft toy or a paint pot?
Use a bucket balance to find out.
• Sometimes, always, never true...
-- A book is the same weight as 12 marbles
-- A shoe is heavier than a sock?
-- A big handful of cotton wool is lighter than three 50p coins?
• Weigh two of your favourite books using wooden bricks. Write their weight. Which weighs more?

In-depth Investigation: Presents

### Planning and Activities

Day 1 Teaching
Make towers of 12 and 16 cubes. What is the same about these towers and what is different? Draw out that one is taller. Point to the four extra cubes in the taller tower. This is the difference. Write: The difference between 12 and 16 is 4. Break off the remaining cubes to show this and represent it on the number line too.
Group Activities
-- Find the difference in height between two towers of cubes.

Day 2 Teaching
Keep this part short to allow children plenty of time for the investigation. Show children how we can make two towers that are different heights. Ask each child to do this. Discuss the towers made by one child. Which is taller? Shorter? What is the difference? Repeat with several pairs of towers.
Group activities
