Estimating and Measuring Time
Let’s investigate!
1. Estimate and then measure how long it takes to… (choose and ring one)
link 20 links throw a 6
2. Colour your answers.
write your name 5 times stick 20 cubes together
I will measure how long it takes in hours days seconds minutes
I will measure how long it takes using a calendar timer stopwatch clock
Estimated time:
Actual time:
Compared to the estimate, the actual time was… (3) faster slower
Try this! The children raced to stack 10 cubes.
Write who was 1st, 2nd, 3rd and 4th.

2. sides the same length sides different lengths
Try this! What capital letter am I?
1. I have 1 straight and 1 curved side.
2. I have 1 curved side only.

Square corners
1. In , draw a dot in all of the square corners.
2. Write M beside the shape(s) with the most square corners.
3. Write L beside the shape(s) with the least square corners.
Try this!
Draw a shape without straight lines. Now, draw a straight line through it.

Counting Groups
Choose a resource to count. In a container, put an amount that you think is between 30 and 90. Do not count!
Draw one of what you are counting.
Make an estimate that is too big.
Make an estimate that is too small.
Make a reasonable estimate. Now count.

Number Hunts
Maths eyes
1. Walk around the school. Find six numbers between 0 and 100. Write them and show them as a sketch.
(a) (b) (c)
(d) (e) (f)
2. Show where each number sits on the number line.
3. Round each of the numbers to the nearest ten.
(a) ➜ (b) ➜ (c) ➜
(d) ➜ (e) ➜ (f) ➜

(b) the smallest number
(c) two other numbers
3. Order the four numbers above. smallest greatest
Finding Patterns
Continue the patterns. 1. 2. 3.
Continue the patterns. Ring the core in each.

4.
Try this! Colour each scarf in a different pattern. Use two colours.
Describing and Making Patterns
Complete the patterns. Each pattern’s core has three elements.
Use to draw three different pattern cores. 1. 2. 3.
Use your cores from to draw three patterns. 1. 2. 3.
Try this!
Use . Choose three colours. How many different patterns can you make?
Record them in your copy.
Growing and Shrinking Patterns
Draw the next two terms and write the numbers.
In , which were...
(a) growing patterns?
(b) shrinking patterns?
Draw the next two terms in the pattern.
How many did you add each time?
D Write the missing terms. Use your 100 square.
1. 1, 3, 5, 7, , ,
2. 6, 8, 10, , ,
3. 30, 25, 20, ,
Let’s talk!
For each pattern in D , explain its rule:
Was it growing or shrinking?
By how much each time?
Try this!
1. Make a growing or shrinking pattern, using materials or numbers.
2. Challenge your partner to work out the rule of your pattern.
How much a pattern changes each time is called its rule.
