Estimating 2

"Sorry, there are no answers for this starter because it depends on the size of your projected image. Perhaps when everyone has had chance to make their estimates, some students could come up to the board and measure the actual lengths of the lines.
Teaching points could include:
:: Appropriate units of measurement to use
:: Appropriate degree of accuracy
:: Using something like the classroom door as a reference length (usually about 2 metres tall)
Of course there is always the issue of correctly adding together the estimated lengths too!"

"I think these are great! So useful and handy, the children love them.
Could we have some on angles too please?"

"This was great, and the students really enjoyed it. Here are the answers I found on a 15.4" screen:

Line 1 - 11.8
Line 2 - 2.9
Line 3 - 16.4
Line 4 - 3.6
Line 5 - 4.0

Hope this helps, keep up the starters!"

"Thanks Mr(s) Teacher for your information. What you might not know is that the lengths of the lines are different everytime this page is loaded (refreshed). The program uses random numbers to produce different lengths so you can use this starter with the same class more than once."
