Learning about Fractions and Decimals is a very difficult concept to learn but suppported by a range of resources, including games, matching cards and magnetic fraction walls and shapes, it certainly becomes a whole lot more meaningful.

Many of our students are visual learners so it is important to remember to provide a range of materials to assist all styles of learning.

Feedback from the students after using these games and puzzles helps to support all aspects of understanding a fraction and decimal.

Pizza Maths

Maths is fun when you get to eat the solution.
As we are learning about fractions we tried to apply our knowledge and strategies for solving fractions into an everyday situation.
The students were given the simple problem:DSCN1617
After a few minutes they shared their solutions. Most were able to draw a model and give an answer. Other students came up and showed their strategies.

Then it was time for a bigger problem. What if we had 9 pizzas to share between 24 students?
This required some real pizzas. We headed to the kitchen to prepare the pizzas. Once they were in the oven the students needed work out what fraction each would receive and what would be the least number of cuts required?

The solutions were surprising!

The students rushed to find a quick solution. Many of them decided thirds would be best with some leftovers. Most were able to draw the solution but struggled to come up with the correct solution.

No-one made a connection to the earlier, simpler problem.

Finally one student surprised herself, by being the first to give the correct answer. The students would only get their slices when they could tell me what their solution was. Another student was the first to realize that you could cut quarters and eighths, making less cuts.

Finally everyone could explain their solutions and strategies.

It was a delicious fraction lesson and one that will make them think more carefully about equal shares in the future-I hope!

Spectacular Decimals

In the words of Holly we have had some ‘quirky learning’ this week about Decimals. There were many “AAHHH” Moments as Decimals began to make sense this week.
We have learnt to make, compare, order, add, subtract and multiply decimals.
We used our Money to help us understand how and when we use decimals in real life and we have also used various Youtube videos to enhance our learning and understanding.

Mark
I have learnt that decimal numbers are greater than zero but less than one. 0 – 1
If you multiply decimals the number will be lower but if you divide a decimal by a decimal the number will increase.

Gemma
I learnt that decimals are related to fractions. They are the tenths, hundredths and thousandths. I can use decimals with money. I can add, subtract and multiply decimals.

Fractions in Flags

DSC_0485

We are learning about Fabulous Fractions. Today we were challenged to design a flag using quarters. Once we got started we were surprised how many quarters we could create. As a class we designed about 20 flags using quarters. Some of us even began using equivalent fractions so the quarters were in eighths and sixteenths also. We shared this fun video at the start just to remind us about some fraction vocabulary.

How many flags can you create using quarters?
