1. Week 2 This week we will discover our surroundings now we are stranded in the rainforest.

2. Lesson 1 The mayday call has been sent. Traffic controllers all over the world are now trying to plot your position. You have told them the rough size of the rainforest and they are measuring the areas of each one to find the one which matches your description.

4. Research Each group should research a different rainforest and present data in their books. 1.Area of the rainforest 2.What percentage is destroyed each year? 3.Any maps which show the deforestation. 4.What is the main purpose for the loss of forest? E.g. logging.

5. Rainforest Data Rainforest NameLocationArea Olympic National Park Washington, USA 2,541.89km² Amazon Rainforest South America 5,500,000km² Madagascar Rainforest Southern Africa 112,600km² Congo River Basin Rainforest Africa 1,780,000km² Data correct April 2016

6. Where are we then? The information given to the controllers was this: “The forest is estimated to be 100,000km²” Our task is to find out which forest is closest to this estimated figure.

7. Lesson 2 The controllers notice that much of the rainforest has disappeared since they last looked and they pass this horrific information to the environmental team. They begin to investigate how much rainforest has been destroyed by comparing maps from different time periods.

8. Here is a recap on last week’s learning How to find the area of compound shapes.

9. What is perimeter? It is the total length of all the sides of a shape. Length + Width + Width

10. But what if you are finding perimeter for a compound shape? Simply add together all the sides lengths! 50m 100m 50 m 120m 20m 100 m Perimeter = 120 + 50 + 100 + 50 + 20 + 100 = _________ m. Perimeter = 120 + 50 + 100 + 50 + 20 + 100 = _________ m.

11. What is the area? It is the measurement of surface covered. Length X Width = m 2 (or mm 2, cm 2, km 2 )

12. But what if you are finding area of a compound shape? You need to split the compound shape into simple shapes! 50m 100m 50m 120m 20m 100m Area B =50m x 20m =______ m 2 Area B =50m x 20m =______ m 2 Area A = 120m x 50m = _____ m 2 Area A = 120m x 50m = _____ m 2 Total Area of shape = Area A + Area B = 6000 m 2 + 1000 m 2 =______ m 2 Total Area of shape = Area A + Area B = 6000 m 2 + 1000 m 2 =______ m 2 A A B B

13. Today, you are conservationists researching deforestation in the Amazon Rainforest. Today, you are conservationists researching deforestation in the Amazon Rainforest. Earlier you learnt that huge amounts of rainforest are being destroyed every day. Earlier you learnt that huge amounts of rainforest are being destroyed every day. In the last minute, and area the size of the main play ground has been lost. In the last minute, and area the size of the main play ground has been lost. Your challenge is to work out both the perimeter and the area of rainforest that has been lost. Your challenge is to work out both the perimeter and the area of rainforest that has been lost. HOW? We are going outside in our groups. HOW? We are going outside in our groups. Take a trundle wheel, worksheet and pencil with you... AND A CALCULATOR! Take a trundle wheel, worksheet and pencil with you... AND A CALCULATOR!

14. What area of rainforest was lost in 1 minute? What area of rainforest was lost in 1 minute? How can we work out how much was lost in an hour? How can we work out how much was lost in an hour? How can we work out how much was lost in a day? How can we work out how much was lost in a day?

15. The next few slides contain examples of rainforest deforestation. Find the areas of the whole picture, then draw known shapes and measure to find the areas of the rainforest depletion.

16. These are the American rainforests. Using known shapes to cover these maps fairly accurately, work out the area of forest left/ lost. Questions Can your work out how much area has been lost? Can you work out the percentage lost/ left? The area of the whole shape would be 100%.

17. This is the Brazilian rainforest and these pictures are only 6 years apart! Find the areas of the deforestation. How much is being destroyed every year? Can you convert to a percentage? The area of the whole shape would be 100%

19. Madagascar Rainforest deforestation

20. Lesson 3 While you are waiting to be rescued, you decide to explore your surroundings. You notice all the fantastic plants and animals. Lots of them are symmetrical and have patterns on them. Some animals sleep upside down! You decide to record your findings for when you get back home. Who knows – you might discover a whole new species!

21. Tangrams They are specific shapes that fit together perfectly. Research your own animals/ plants/ trees from the rainforest and recreate them using the tangram shapes. Remember… no gaps! (see Tanazon Rainforest Lesson 1 pdf)

22. Animal tangrams – can you do better?

23. Activity 2 – Lesson 3 Rotation Cut out your animal. Can you make your animal sit on the branch? Hang from the branch? What rotations have you achieved? (See Tanazon rainforest lesson 2 pdf.) Also see additional resources and activities.

24. http://nrich.maths.org/6987 This link gives ideas for how to rotate shapes around a central point. Create flowers/ animals etc using this technique. Make different shapes out of card to rotate. Use shapes of rainforest leaves/ petals. Can you recreate the plants of the rainforest?

25. Rotate the points 90° into each quadrant around the point (0,0). What would the new co- ordinates be?

26. Lesson 4 Translation means to move. See the fern leaves on the plant here? These look like they have been translated as they appear identical as though they have translated down the plant stem.

31. Just remember… the top number of the vector moves the shape side to side. The bottom number moves the shape up and down.

32. Lesson 5 Reflection/ symmetry – (butterflies, then reflection in 4 quadrant grid) Next…some slides showing the beautiful, symmetrical rainforest!
