Maths sticks - Week 3

We are learning about measurement.  We need to make our name out of 50 maths sticks.  We needed to make each one of our letters 20 centimetres tall or our name one metre long.  I did the one that you need to make each letter 20 centimetres tall.  We need to have a starting point and a finishing point which means you need to have your name starting at cm which stands for 0 and the finishing point will be at the end of your ruler.  A little ruler would be about 30 centimeters long.  With our name we had to count up how many of each colour maths sticks and then we had to work out what was the total value of your name.  But we didn't do our name, the teacher gave us a sheet for us to work on.  So say there were 3 blue, 4 red and 5 yellow we had to work out what it was.  And just say the yellow are $10, the blue $5 and the red $2 and we had to work it out so here is an example, so there were 5 yellow and they were worth $10 and 10+10+10+10+10=50, so now you have 50 and now the blue are worth $5 and there were 3 blues so lets count 5,10,15=15, now we have 15, now the red. The reds are worth $2 and there are 4 of them.  Lets count again 2,4,6,8,10, now we have 10 so 10+50+15=75 so the total value was $75.

  1. Great explaining Sienna, you have been clear about the activity. Your skip counting is great, remember that we can use times tables (multiplication) as well to work out the number e.g. 5 x 10 = 50.
