    Partition, rearrange, regroup and rename two- and three-digit numbers using standard and non-standard groupings; recognise the role of a zero digit in place value notation <ul> <li>comparing the digits of a number with materials grouped into hundreds, tens and ones, and explaining the meaning of each of the digits in the materials</li> <li>renaming numbers in different ways using knowledge of place value; for example, renaming 245 as 24 tens and 5 ones or 2 hundreds and 45 ones</li> </ul>

    Add and subtract one- and two-digit numbers, represent problems using number sentences and solve using part-part-whole reasoning and a variety of calculation strategies <ul> <li>using the associative property of addition to assist with mental calculation by partitioning, rearranging and regrouping numbers using number knowledge, near doubles and bridging-to-10 strategies; for example, calculating 7 + 8 using 7 + (7 + 1) = (7 + 7) + 1, the associative property and near doubles; or calculating 7 + 8 using the associative property and bridging to 10: 7 + (3 + 5) = (7 + 3) + 5</li> <li>using strategies such as doubles, near doubles, part-part-whole knowledge to 10, bridging tens and partitioning to mentally solve problems involving two-digit numbers; for example, calculating 56 + 37 by thinking 5 tens and 3 tens is 8 tens, 6 + 7 = 6 + 4 + 3 is one 10 and 3, and so the result is 9 tens and 3, or 93</li> <li>representing addition and subtraction problems using a bar model and writing a number sentence, explaining how each number in the sentence is connected to the situation</li> <li>using mental strategies and informal written jottings to help keep track of the numbers when solving addition and subtraction problems involving two-digit numbers and recognising that zero added to a number leaves the number unchanged; for example, in calculating 34 + 20 = 54, 3 tens add 2 tens is 5 tens, which is 50, and 4 ones add zero ones is 4 ones, which is 4, so the result is 50 + 4 = 54</li> <li>using a physical or mental number line or hundreds chart to solve addition or subtraction problems by moving along or up and down in tens and ones; for example, solving the problem ‘I was given a $100 gift card for my birthday and spent $38 on a pair of shoes and $15 on a T-shirt. How much money do I have left on the card?’</li> <li>using Aboriginal and Torres Strait Islander Peoples’ stories and dances to understand the balance and connection between addition and subtraction, representing relationships as number sentences</li> </ul>

Two-Digit Addition with Partitioning

Partitioning is a fundamental strategy in mathematics that helps students break down complex numbers into more manageable ones. By splitting numbers into tens and ones, students can add more easily and with greater accuracy. This method not only simplifies the process but also deepens their understanding of place value.

This poster and set of two worksheets has been designed by our team to support you in teaching two-digit addition with partitioning to your students. Here’s what’s included:

  • Ice Cream-Themed Poster – This vibrant and visually appealing poster explains the concept of partitioning in a fun, relatable way… using ice cream scoops!
  • Worksheet 1: Partition for Addition – In this activity, students practise splitting two-digit numbers into tens and ones, then adding them together step by step.
  • Worksheet 2: Tens and Ones –  This worksheet challenges students to partition given numbers into their tens and ones components.

The poster downloads as a colour PDF whereas the worksheets download in black and white. 

Differentiation for Two-Digit Addition

If you’re needing to adapt this activity to meet the needs of all learners, check out these suggestions from our experienced teacher team:

  • Use Manipulatives – Help your less confident students partition two-digit numbers by providing manipulatives such as Base 10 blocks. These learning tools allow students to physically partition the numbers on the worksheet into tens and ones, making the written algorithms seem less daunting.
  • Partition Numbers in Multiple Ways – Challenge your students to partition the numbers on the worksheet in multiple ways. For example, the number 56 could be partitioned into 5 tens and 6 ones, 4 tens and 16 ones, 2 tens and 26 ones (and so on).
