Planning and Activities
Day 1 Teaching
Use 10p and 1p coins, then base-10 equipment to make 2-digit numbers.
Group Activities: T with Y1 or Y2
Y1 -- Make prices on labels using 10p and 1p coins. Roll dice to determine number of 10ps and 1ps to add together to make a 2-digit amount.
Y2 -- Make 2-digit numbers using base-10 equipment. Roll dice to determine the number of sticks of 10 and single cubes to add together to make a 2-digit number; write place value additions.
Day 2 Teaching
Use place value cards to make 2-digit numbers, mark on a beaded line.
Further Teaching with Y2
Compare 2-digit numbers using > and <. Mark on a landmarked line, think of a number in between.
Group Activities: T with Y2
Y1 -- Make numbers on a bead string and record as an addition number sentence. Make 2-digit numbers using place value cards and position them on a beaded line.
Y2 -- Compare two 2-digit numbers, using symbols to correctly write inequalities.
Day 3 Teaching
Ask Y1s to place numbered tags on a bead bar and Y2s to round to the nearest multiple of 10. Discuss numbers that sit halfway between the target multiples, and the convention to round up.
Further Teaching with Y1
Think of numbers between neighbouring multiples of 10 on the bead bar.
Group Activities: T with Y1
Use the in-depth problem-solving investigation ‘Square order’ as today’s group activity.
Or, use these activities:
Y1 -- Find numbers between two neighbouring multiples of 10 and label these on a beaded line. Create 2-digit numbers and order them from smallest to largest.
Y2 -- Round 2-digit numbers to the nearest 10.
