# Maths Year 3 Spring Time and Data

Each unit has everything you need to teach a set of related skills and concepts.

First time using Hamilton Maths?

The PowerPoint incorporates step-by-step teaching, key questions, an in-depth mastery investigation, problem-solving and reasoning questions - in short, everything you need to get started.

All the other resources are there to support as-and-when required. Explore at your leisure - and remember that we are always here to answer your questions.

## Unit 1 Tell time to 5 minutes; Roman numerals (suggested as 3 days)

### Objectives

Tell the time to nearest 5 minutes; Roman numerals
Unit 1: ID# 3581

National Curriculum
Meas (iv) (v)

Hamilton Objectives
33. Tell and write the time on digital and analogue clocks (including those with Roman numerals).
34. Record times in hours, am and pm.

### Planning and Activities

Day 1 Teaching
Show the ITP Tell the Time. Click to show 9 o’clock. Click round to show the 5 minutes past to half past 9. Then discuss how these times match to digital clock times. Show the 5 minute intervals through to 10 o’clock.
Group Activities
-- Read, write and make times to 5 minutes past the hour on analogue and digital clocks, including those with Roman numerals.

Day 2 Teaching
Launch the ITP Tell the Time and set the clock to 5 o’clock. Work out what the clock would look like in increments of 15 minutes, ask children to write down the time in digital format. Give out small analogue clocks and ask children to match o’clock, quarter past and quarter to digital times.
Group Activities
-- Read, make and write times to the next hour, to 5 minutes, on analogue and digital clocks.
-- Find the time 15 minutes later and show it on analogue and digital clocks.

Day 3 Teaching
Launch a clock on the web (see address). Press the times button and children write matching digital times. Introduce am and pm and discuss how it is hard to tell if it is am or pm on an analogue clock.
Group Activities
Use the ‘Dodgy digital clock’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Order times in different formats, including am and pm.
-- Make and write times on analogue clocks and in digital format.

### You Will Need

• Mini-whiteboards and pens
• ITP Tell The Time
• Analogue clock with Roman numerals
• Small analogue clocks and digital clock
• ‘Analogue clocks’ sheet 1 (see resources)
• Large analogue clock
• Large piece of paper and glue
• ‘Time’ sheets (see resources)
• ‘Analogue clocks’ sheet 2 (see resources)

### Mental/Oral Maths Starters

Day 1
Units of time (pre-requisite skills)

Suggested for Day 2
Pairs of multiples of 5 with a total of 60 (simmering skills)

Suggested for Day 3
5 times table (simmering skills)

### Worksheets

Day 1
Write and draw corresponding analogue and digital clock times.

Day 2
Match analogue clock times to digital clock times and vice-versa.

Day 3
Order analogue and digital times from earliest to latest, including am and pm.

### Mastery: Reasoning and Problem-Solving

• Draw the hands on a clock to show:
10 past 10
10 to 10
11:45
Quarter past 3
12:40
• True or false?
1:50 is the same as 10 minutes to 2.
5 o’clock am is 12 hours later than 5 o’clock pm.
15 minutes before 6 o’clock is 5:15 on a digital clock.
If the hour hand is pointing to VI, it is six o’clock.
If the minute hand points at XI, it is nine o’clock.
• If the clock hands make a straight line on an analogue clock, what times could the clock be showing?

In-depth Investigation: Dodgy Digital Clock
Children work out which times won’t show correctly because of a faulty segment in the digital display.

### Extra Support

Pink Past and Blue To
Telling the time to the quarter hour on analogue and digital clocks

## Unit 2 Time events; units of time; pictograms (suggested as 2 days)

### Objectives

Time events; units of time; pictograms
Unit 2: ID# 3593

National Curriculum
Meas (v) (vi)
Stats (i) (ii)

Hamilton Objectives
34. Record times in seconds, minutes, hours, months, years.
36. Interpret and represent data on scaled bar charts, pictograms and tables, and solve problems using these.

### Planning and Activities

Day 1 Teaching
Start a stop watch. Children close their eyes and raise hands when they think a minute has gone by. When all children put up their hands (or after 2 mins!), say which children put up their hands at roughly the right time. Discuss timing a minute by counting 60 seconds.
Group Activities
-- Time events in seconds and record them on a bar chart.

Day 2 Teaching
Discuss which month has the most birthdays. Provide birthday months for a couple of classes in the school. Say that we will draw a pictogram of the results. Create a tally chart and then agree an image for the pictogram, e.g. a circle to represent a birthday cake!
Group Activities
Use the in-depth problem-solving investigation ‘Real statistics’ from NRICH as today’s group activity.
Or, use the activity below:
-- Draw and interpret a pictogram where 1 symbol represents 2 units.

### You Will Need

• Stop watch
• Mini-whiteboards and pens
• Large sheets of paper
• Class registers
• Flipchart
• Large piece of squared paper

### Mental/Oral Maths Starters

Day 1
Months of the year (pre-requisite skills)

Suggested for Day 2
2 times table (simmering skills)

### Worksheets

Day 1
Present information from a table on a bar chart marked in steps of 10 seconds and derive facts from it.

Day 2
Complete a pictogram where 1 symbol represents 2 items, and derive facts from it.

### Mastery: Reasoning and Problem-Solving

• Say which things would be timed in seconds, which would be timed in minutes, and which in hours.
