5th December
Today in maths we have been thinking about number sequences. We have been trying to identify the "rule" by which a sequence has been created as well as completing sequences.
We followed up work in a previous week's maths topic in ICT when we used a spreadsheet program to produce a graph plotting data based on a table we created of details about rectangles which had the same perimeter. We began by producing a table of lengths and widths of rectangles which had a perimeter of 20 cm. Then we used the function option to calculate the areas of these rectangles before plotting all this data on a line graph.
This afternoon we planned and carried out an investigation as part of our work on light. A clothing company had asked us to test different materials to see which would be the best one to use to create a reflective strip on jackets for cyclists to use at night. We had to plan an experiment, make notes about how we were going to make this a fair test and then do the experiment.
