  Introduce the students to the concept of birthday party’s and discuss what happens at these. Explain that this week they will be working at different stations to help prepare for a party. In each of these stations they will need to measure volume accurately. Points that may need to be discussed as work progresses include:

• The importance of estimation and the value of accurate estimation.
• The relationship between millilitres and litres.
• Reading volumes and scales to an appropriate accuracy. Sometimes it will be possible to estimate half way between marked volumes.

Station One

In this station students accurately measure the volume of a variety of different drinking glasses.

Student instructions (copymaster one)

In this station you need to estimate and measure the volume of different glasses for drinks at the party.

1. Estimate the volume of each of the glasses in mLs. Record your estimates.

   Which glass do you think will hold the most?
   Which will hold the least?
   Which glasses will hold a similar amount?

2. Use the measuring equipment to measure the volume of each of the glasses. Record your results in a table as you work.

   Compare your results with your estimates. How close were your estimates?

   Which glass held the most?
   Which held the least?
   Which glasses held a similar amount?

    

Station Two

In this station students accurately measure the volume of a variety of bowls that could be used to make jelly.

Student instructions (copymaster two)

In this station you need to estimate and measure the volume of different bowls used to make jelly for the party.

1. Estimate the volume of each of the bowls in litres and mLs. Record your estimates.

   Which bowl do you think will hold the most?
   Which will hold the least?
   Which bowl will hold a similar amount?

2. Use the measuring equipment to measure the volume of each of the bowls. Record your results in a table as you work.
3. Compare your results with your estimates. How close were your estimates?

   Which bowl held the most?
   Which held the least?
   Which bowls held a similar amount?

If each packet of jelly made 1 litre how many packets would be needed for each bowl?
How many packets would be needed for all the bowls?

 

Station Three

In this station students make baskets to hold lollies and measure the volume of the baskets they have made.

Student Instructions (copymaster three)

In this station you will make baskets to hold lollies for the party and measure the volume of the baskets you have made. Can you make three baskets that hold different amounts?

1. Make a basket: Take a rectangular shape and cut squares of the same size out of each corner of the rectangle. Cut out the shape and tape up the sides. Cut a strip for a handle and tape it on.

2. Estimate the volume of your basket. Record your estimates on a table.
   Which basket will have the greatest volume?
   Which will have the least?
3. Measure the volume of your baskets using the sand and the measuring equipment. Record your results in a table as you work
4. Compare your results with your estimates. How close were your estimates?

   Which basket held the most?
   Which held the least?

Station Four

In this station students measure the volume of a variety of cake tins and predict which recipe would be best to use for each tin.

Student Instructions (copymaster four)

In this station you need to measure the volume of the different cake tins, then decide which recipe mix would be best for each tin. Remember that the cakes will rise when they are cooked!

1. Estimate the volume of each of the cake tins. Record your estimates on a table.
2. Measure the volume of each of the cake tins using water and the measuring equipment. Record your measurements.
3. Compare your results with your estimates. How close were your estimates?

   Which tin held the most?
   Which held the least?

4. Which of the recipes below would be best for each tin? You will need to add up the volume of ingredients and allow for the cake to rise when baked to be able to make a good decision.
