Year 4 Mathematics
Time Me Task
Task Outline:
You will need to complete several different physical activities such as starjumps, running laps, hoop lifts and skips.
For each activity you will need to time the activity accurately and record your score on a table.
Before you begin each activity you need to predict what score you think you can achieve.
To complete the task, you need to present the table showing your predictions and your actual scores and write a
statement to explain the results.
Equipment Required:
Stopwatches or clocks/ watches with an accurate minute timer.
Equipment as required such as skipping ropes, hoops, markers.
Procedure:
1. First form a group of three students. One student is the timekeeper, another student is the recorder (to keep a
total of the repetitions) and the third person completes the activity. Each student must take a turn to do each
role. Each student must complete every physical activity.
2. Before beginning, you must predict how many repetitions you can do. Record this on your table. Then
complete the activity within the required time and record your score. Compare your score to your prediction –
what do you notice? Write a statement to explain your thinking.
3. Based on the first scores you recorded (for 1 minute), now predict your scores for the same activities, with a 3
minute time period. What do you predict your score will be? Record your prediction, and explain why you
have calculated that score.
4. Complete the activities for three minutes and record your scores. Compare the results to your predictions.
Write a statement to explain your thinking.
5. Continue to predict, complete the activity and record actual scores for the same activities for another 5
minutes. What do you notice?
6. Now predict what your scores would be for 10 minutes. Write a statement to explain your thinking.
7. Use the information in your table to draw a graph displaying your experiment.
8. Your graph should include your predictions and actual scores for 1 minute, 3 minutes and 5 minutes. You can
use technology to create the graphs if you choose.

C
Uses a stopwatch, digital or analogue
watch/clock to consistently measure time
periods of 1 minute, 3 minutes, 5 minutes,
and 10 minutes.
.
Uses a stopwatch, digital or analogue
watch/clock to measure time periods of 1
minute, 3 minutes, 5 minutes, and 10
minutes with satisfactory accuracy.
Comprehensively records data from
activities in a table and independently
creates detailed graphs from the data in the
table.
Records data from activities into a table with
satisfactory detail and follows class models
to create a graph showing some of the data
in the table.
Comprehensively refers to data when
making inferences
Makes occasional reference to data when
making predictions.
Comprehensively identifies unexpected
variation in data – “My scores didn’t get as
high as I predicted because I got more and
more tired as the time got longer.”
Makes some links to unexpected variation
“I thought my score would be… but it was
only …. I got tired.”
Data can be collected to support or
adjust predictions
Data collected from experiments or
observations can be organised in
tables and graphs and used to
respond to questions about the
likelihood of possible outcomes of
events.
Collected data can be used to
justify statements and predictions.
Sets of data contain expected or
unexpected variation, and this may
mean that additional data are
needed.
Thinking and
Reasoning
Make predictions based on
experience in similar situations.
Makes accurate predictions about physical
activity over longer time periods by applying
mental computations or similar strategies
and makes logical inferences about
variations in data.
Makes reasonable predictions about physical
activity over longer periods of time using
repeated addition or similar reasoning. Some
thinking about possible variations evident.
Communicating
Make statements, predictions,
inferences and decisions based on
mathematical interpretations.
Comprehensively refers to collected data
when making inferences and predictions and
uses detailed explanation of mental
computations when generating solutions
“If I could do 10 star jumps in 1 minute then I
should be able to do 3 times that many – 30
jumps in 3 minutes.”
Makes a sound statement of prediction
based on some reference to data and
provides a sound strategy using mental or
written computations to explain solutions
“I think I could do 30 star jumps because it is
3 times longer.”
Identify and use mental and
written computations, estimations,
representations and technologies
to generate solutions and check for
reasonableness of solutions.

Reflecting
Reflects on own learning about
time and physical activity.
Perceptive statements about own learning
includes reference to the effect of fatigue
and tiredness on physical activity as the time
for the activity increases. “I realised that if I
do skipping or star jumps for twice as long,
that doesn’t mean that I will do twice as
many because I get tired and slow down.
That changes my score.”
Reflects on own learning using a relevant
reflection about something new learnt about
time and physical activity. “I realised that I
get tired over a longer time and slow down.”
