Maths

This week for Home Learning in Room 18 we had to do a maths blog post. We had to show two strategies for the question. The strategies I used are Rounding and Compensating and Place Value. These are the 2 questions that we could pick 28x6 or 36x18. I picked 28x6 because it was a good one to do.

Here is how I worked it out.

Place Value
28x6=?
28x5=140(20x5=100 + 8x5=40)
28x1=28
140+28=168

Rounding and Compensating
28x6=168
+(2x6=12)
30x6=180-12(2x6)=168

So that's how I got my answer 168.

  1. Excellent Jonty! Well done! It's great how you wrote two strategies. Did it take you a long time? The Place value helped me heaps. Thanx so much. It is easy to understand because you wrote it step by step!
