Maths Year 1/2 Spring Place Value and Number

Each unit has everything you need to teach a set of related skills and concepts.

2-digit place value (suggested as 3 days)

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.

Short Mental Workouts

Day 1
Count in 1s and 10s to 100

Day 2
Recite numbers to 100

Day 3
Place value


Day 1
Y1: Use place value to write then draw amounts of money.
Y2: Write totals of 10s and 1s; complete place value additions.

Day 2
Y1: Locate 2-digit numbers on a beaded line.
Y2: Complete a table showing inequalities.

Day 3
Y1: Find numbers between pairs of neighbouring 10s numbers.
Find numbers on a beaded line and label. Label two numbers between these.
Y2: Round prices <£1 to the nearest 10p.

Mastery: Reasoning and Problem-Solving


  • Use place value cards to create these numbers:
    46, 72, 81, 18.
  • For each pair, circle the number that has more 10s.
    (a) 34 and 51
    (b) 14 and 41
    (c) 59 and 61
    (d) 80 and 28
  • How many 10ps and 1ps in each amount?


  • Fill in the missing numbers:
    49 = 9 + ☐
    ☐ – 7 = 30
    90 = 94 – ☐
  • Write the missing number or symbol: < or >.
    87 ☐ 78
    73 < ☐
    14 ☐ 41
    39 ☐ 62
    19 > ☐ > 14
  • Round these numbers to the nearest tens number:
    26, 37, 61, 75, 94, 86, 55
  • Write all the numbers that round to 60 as the nearest 10.

In-depth Investigation: Square order
Children place four digit cards on a grid to create 2-digit numbers and order them. They move the digits around to make smaller/larger numbers.
