Place Value – On The Blocks… 1. Read the numbers shown by the green arrows. 2. What number is labelled by the blue arrow? b a c d You may need mini-whiteboards. 3. What number might the arrow at ‘a’ be indicating? about 10,230 Is 10,230 nearer to 10,200 or 10,300? We can say that 10,230 rounded to the nearest hundred is 10,200. What are b, c and d rounded to the nearest 100? © Hamilton Trust Term 1 Week 1 Day 3
