Today in class we saw how we can play by building different shapes changing their area, or their perimeter or both!
Here is a short video to revise what we saw in class!
1) Here are some activities for you to do after class and we will share the results next Wednesday!
2) Watch the video in the link below and use the same idea to complete the chart.
3) Watch this video and solve the problems WITHOUT DRAWING.
- If I have a board of 36 cm2,
a) how many different rectangular shapes can it have?
b) calculate and write the perimeter of each one.
b) which shape has the largest perimeter?
2. If I have a board of 34cm of perimeter and 42cm2 of area,
a) how many different rectangular shapes can I have?
b) if there are more than one, choose one and calculate the length and width.
4) Construct shapes making as FEW changes to the central shape as possible, so that they fulfill the conditions
.Look carefully BEFORE you start. You will have to print and paste/draw this page in your folder.
- Were some cells easier to complete than others?
- Could you complete all the cells?
- Could you find easy ways of calculating what you needed?
- Can you find any relation between area and perimeter’
HAVE THIS SET PRINTED OR DRAWN FOR WEDNESDAY 23rd! YOU WILL BE WORKING IN GROUPS AND IT´S VERY IMPORTANT THAT YOU ALL HAVE THE MATERIAL READY!
HAVE A GREAT AFTERNOON!!!
