Understanding Venn Diagrams

In our Maths lesson today, we have been getting hands on with Venn diagrams. To help us to understand how they can be used to represent data, we have spent some time in the hall physically sorting numbers into given criteria. Can you remember where the numbers that do not fit the criteria of the hoops go?

Cakes, Icing, Tasting, Trying…

We have been testing out our skills with food recently. As part of this we have had to work in groups finding out the exact quantities we would need based on an original recipe. We started out with the recipe for our butter cream for 10 cakes. In our groups, we had to calculate what we would need for the total of cakes we would be decorating. Following this, we had to work together to measure out our ingredients, mix, decorate and finally taste test our final product.

What did you think of your cake? Was it a success or will you do something differently next time?

Warning… Boring bit ahead.

Objectives included:

  • Prepare ingredients hygienically using appropriate utensils.
  • Measure ingredients to the nearest gram accurately.
  • Follow a recipe.
  • Measure accurately and calculate ratios of ingredients to scale up or down from a recipe.

Maths Challenge of the Week – Santa’s Deliveries

Santa’s Deliveries

For a success card, find the solution but remember to explain how you found the answer and any working out that you used. Good luck!

Father Christmas has a problem! He has found that each year he is delivering more and more Christmas presents. He has been keeping a record of this for the past few years  and is worried about how many presents he will be delivering after the 15th year. Unfortunately, he has lost some of the results and only has the first few years.

Here is what he has left:

Year 1 – 1 Present delivered

Year 2 – 4 Presents delivered

Year 3 – 9 Presents delivered

Year 4 – 16 Presents delivered

Year 5 – 25 Presents delivered

Year 6 …. The rest is missing

Santa wants to know how many presents would be delivered in the 15th year? Can you find a link between the year and the number of the presents delivered? Maybe that will help you find the answer?

For a success card, find the solution but remember to explain how you found the answer and any working out that you used. Good luck!

Angles

Earlier this week we have learning about angles in triangles. We worked out the missing angles  using 180 degrees and we learned that a parallelogram has two angles the same at the bottom. We had to work out what they were on Mathletics and used Mathletics to learn more on angles.

 

Finding missing angles.

This week in numeracy we have been finding missing angles on a straight line, inside triangles and inside quadrilaterals.

What can you recall?

  • How many degrees are there on a straight line?
  • How many degrees are there inside a triangle?
  • How many degrees are there inside a quadrilateral?
  • How many degrees are there in a full turn?

Remember to compete the Mathletics activities you have been set. Aim for 70% or higher in each task.
