Try to solve the problems independently.
You may use diagrams to explain your thinking.
We will discuss as a group what strategies you used to solve the problems
WALT: use multiplicative and/or additive strategies to solve measurement problems.
A student measures her height with a 30 cm long ruler.
She finds that she is four and a half rulers high. How tall is
she in cm? 30cmx4=120cm ½ of 30cm=15cm 120cm+15cm=135cm
A student is told that they are 1.45 m tall. How tall is this in cm? 145cm
If it takes 3 hours to drive 210 km, what was the average speed of the journey?
210 divided by 3=70kph
A class of 28 is split into small groups. How big can those groups be?
Factors of 28 1 2 4 7 14
A car, travelling at an average speed of 70 km/ph is in a journey of 210 km.
How long will the journey take? 70x3=210km so it will take 3 hours to get there.
A long distance swimmer takes 80 strokes to swim 100 metres.
He wants to swim across Lake Taupo, a distance of 4200 metres.
a. How many strokes will it take for him to swim across the lake?
b. If he can swim at a rate of 60 strokes per minute, how many
minutes could he swim across the lake in?
c. Can he expect to beat the 2015 champion swimmer who
crossed the lake in a time of 51 minutes and 48 seconds?
No because he did it in 56 minutes and the swimmer did it in 51 minutes.
