Day 2 Teaching
Display a landmarked 0-10,000 line and ask children to place 6000, 4500, 1250 and 9999 on the line. Then use a washing line to represent numbers 0 to 10,000. Ask children to place numbers on this line.
Group Activities
Use the in-depth problem-solving investigation ‘The Thousands Game’ from NRICH as today’s group activity.
