# Learning By Topic KS2: Sustainable Eating and Mathematics

What are the deforestation figures for the Amazon Rainforest over the past decade? Have they increased or decreased?

Calculate the volume of planter boxes or garden beds you have access to.

Create a number code for the alphabet (e.g. a =1 b=2 be a bit more adventurous than this example) write your theme words using this code – can anyone crack your codes?!

Now ask an adult to write some addition, subtraction, multiplication and division sums in this code. Can you decode these and then solve them?

Find the perimeter and area of your garden, planter box and/or garden bed.

Measure different angles around your garden or local environment. Maybe take some photos and then sort them into a table with the heading, acute angles, right angles, obtuse angles, straight angles and reflex angles. Top Tip: You can either print photos for this activity or construct your table on the computer and cut and paste the photos in.

From your science activity that involved you planning and planting your own fruit and veg, calculate how much your family might save in their weekly shopping over a year if everything you plan to plant thrives. To work this out you will also have to take into account the costs of the equipment you need to plant your fruit and veg.

What 3D shapes can you identify around your garden? Can you list/label the properties for each shape? E.g. number of faces and vertices.

Once a seedling appears (from your Science activity) measure the height of it every morning and every night until the bud appears. Then plot these measurements on a line graph to show its growth/progress.
