We have been learning about squared numbers and the phrase ‘to the power of’.
I like how 10 to the power of 8 is just 1 with 8 zeros on the end a much quicker way to write it. I even learnt that squared numbers make a square when coloured in and the square root is the opposite of a squared number.
The first thing we tried to do was list all the fractions we could think of, randomly it didn’t work. When we started with a whole, then moved to half and two halves onto 1/3, 2/3 and 3/3, everyone got into the discussion until we reached 10/10.
Then we looked at which one all meant one whole, 1/1, 2/2, 3/3, 4/4, 5/5 … 10/10 and repeated for what a half was 1/2, 2/4. 3/6,4/8 and 5/10. They even noticed that not all fractions sets could show half.
We then discussed how 1/10 meant that a whole was divided into 10, so tried dividing 1 by 10 on a calculator, and then discussed the place value of decimals and what they saw on the calculator.
Then with a chart looking like this students had to find the decimal for each fraction and then the decimal.
Do you know how to use the decimal to work out the percentage?
After setting up the tables with 4 pieces of A4 paper, scissors and tape. We talked about capacity and what it might be. Students explained that it was similar to volume and showed how much a container might hold.
They had to make two different size containers using the same size paper. One was tall and thin the other was wider and shorter.
Some students thought the tall one would hold more others thought the wider one.
Ms brought out the popcorn and each gorup had one bag. Each group had a different way to measure too.
One group decided to pour popcorn from the thin container to the wide one. Another group did the opposite wide to thin, a third group filled both container and then counted how much popcorn was in each container. The fourth group put the thin container on top of the wide one with a piece of paper inbetween, filled the top.
We have been comparing the volume of containers to do this we need to work out the volume of a countainer. The height of our containers that we created changed by 1 cm. I can’t wait to see the results so I can make sure I have the best container for POPCORN!
