### 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.
