Package 2-3: Measuring muffins

In this task your child will develop measurement skills through baking muffins or another recipe of your choice.

Week 3 - Package 3 - Year 5 and 6 Mathematics - Measuring muffins

Things you need

Have these things available so your child can complete this task.

Ideal

  • Ingredients for Blueberry Muffin recipe (see below)

  • Sieve, large bowl, wooden spoon, spoon, oven, 12 hole muffin tin, skewer ,wire rack

  • Measuring jug, weighing scales

  • Oven gloves

  • Paper and pencil

  • Counter, coins or other small set of countable objects such as Lego bricks

Back up

  • If your child has allergies or does not like blueberries use one of your own recipes for muffins or biscuits. The recipe should be in metric measurements – grams, millilitres

  • See your own recipe for requirements

  • Conversion measurements if needed

Before you start

This is a fun activity that is also an opportunity to spend some time being creative with your child. It is important to allow enough time for the practical activity so that it doesn’t become stressful. Also you may want to decide ahead of time who is going to be responsible for cleaning the dishes and who will clean the work space.

Remember this is a shared activity and you will be using a hot oven. If you prefer you could take charge of putting things in and taking things out of the oven.


Make sure you have all of the ingredients and equipment ready for your activity and a damp cloth or two for if things get messy.

What your child needs to know and do

Your child is going to help you bake muffins or another recipe of your choice that makes muffins or biscuits.

Blueberry Muffin Recipe

  • 295g self-raising flour

  • 90g salted butter

  • 150g brown sugar

  • 125g fresh blueberries

  • 250ml milk

  • 2 eggs, lightly beaten

Method

  1. Preheat the oven to 180 degrees C (160 degrees fan forced) and grease a 12-hole muffin tin.

  2. Sift the flour into the large bowl. Using fingertips, rub the butter into the flour until the mixture looks like fine breadcrumbs. Stir in the sugar.

  3. Make a well in the centre of the flour mixture and pour in the blueberries, milk and lightly beaten eggs. Gently stir until just combined.

  4. Carefully spoon the mixture into the greased tin.

  5. Bake for 25 minutes or until a skewer inserted in centre of 1 muffin comes out clean.

  6. Leave the muffins in the tin for 5 minutes before turning out onto a wire rack to cool.

What to do next

Before the muffins are shared and eaten, but after the washing up has been done ask your child to consider the following questions.

  • Imagine that the muffins have been baked for a family of four. How many would each person in the family get?

  • What other sized groups of people could you divide the muffins between and ensure that everyone got at least 1 muffin?

Ask your child if they would like to bake the muffins for their class at school when everyone is able to go back. The recipe gives the ingredients to make enough batter for 12 muffins. How many batches of the recipe would they have to make in order to make sure everyone in their class (and the teacher of course) gets at least one whole muffin?

Level 1: If you think this is going to be tricky for your child, stick to whole multiples, for example, they might double the recipe for 24 or triple for 36.

Ask your child then to rewrite the recipe so there is enough of each ingredient to make 2 or 3 batches.

On completion ask your child if this is a practical way of baking. Would all of the ingredients fit into the bowl? Do you have another muffin tin? Would it be better to bake the batches one after the other and leave the recipe as written?

Level 2: For students who are confident with decimals and fractions they could rewrite the recipe to make exactly 30 muffins.

On completion ask your child if this is a practical way of baking. Would all of the ingredients fit into the bowl? Do you have another muffin tin? Would it be better to bake the batches one after the other and leave the recipe as written?

Eat, and enjoy, the muffins.

Options for your child

Activity too hard?

You may need to support your child with reading the scale when measuring the ingredients.

Give your child 12 counters, coins or lego bricks to divide into as many equal groups as they can.

See option 1 above.

If your child has difficulty multiplying the amounts in the recipe by 2 or 3 ask if they can think of another way of doing it. If necessary a calculator can be used.

Activity too easy?

What would happen if there were 5 people in your family and everyone wanted their fair share? Draw a diagram of how you would share the muffins so that everyone got an equal share. This could take some time. What is the exact number of muffins that each person gets? This question could be answered as a fraction or as a decimal fraction. See option 2 above.

Extension/Additional activity

Counting the cost

Ask your child to draw up the following table on a piece of paper or on their device. Alternatively you could print out this table.

Ingredient Cost per item Cost for 12 muffins Cost for 48 muffins

Blueberries




Milk




Brown Sugar




Salted Butter




Eggs




Self Raising Flour




Total Cost




Explain to your child that if you didn’t have any of these ingredients in your pantry you would have to buy them as packaged. This would mean that the cost for 12 muffins would be the same as the cost for all of the ingredients. This means that working out the costs of baking isn’t as straightforward as it might seem.

Check that your child understands that 48 muffins would be four times the original number of muffins. For this column they will need to refer back to the original recipe and work out how much they will need to make 4 times the amount. Then they will need to refer back to the package size to work out the costing.

Was your child surprised by how little difference in cost there is for making 12 muffins and making 48 muffins? Can they explain why?
