Teaching and Group Activities for Understanding
Day 1 Teaching
Mark 2-digit numbers on 0–100 beaded, landmarked and empty lines. Mark 3-digit numbers on 0–1000 landmarked lines and place numbers between multiples of 100.
Group Activities: T with Y3
Y3 -- Place 2-digit numbers on empty and landmarked lines.
Y4 -- Place 3-digit numbers on empty and/or landmarked lines.
Day 2 Teaching
Use skills learned to place numbers between 0 and 100 to place numbers between 100 and 200, then on 0–1000 landmarked lines.
Further Teaching with Y4
Place 4-digit numbers on 0 to 10,000 landmarked lines.
Group Activities: T with Y4
Use the in-depth problem-solving investigation ‘Round the Three/ Four Dice’ from NRICH as today’s group activity.
Or, use these activities:
Y3 -- Mark numbers on 100–200, or 0–1000, landmarked lines.
Y4 -- Place multiples of 50 on 0–10,000 landmarked lines, find the number halfway between them; order 4-digit numbers.
Day 3 Teaching
Play a game comparing 3-digit numbers (Y3) and 4-digit numbers (Y4) and place them on landmarked lines.
Whole Class Activity: T to circulate
-- Play a game comparing 3-digit numbers (Y3) and 4-digit numbers (Y4) and place them on landmarked lines. The winner of each round wins a digit card, which they use to try to make the larger number once the game has finished.
