Part-Part Whole – Year 2

Part-Part Whole gives teachers a structured week of Year 2 mathematics learning that progresses from concrete part-and-whole relationships to flexible mental computation. Students identify and model two parts of a whole, recombine parts, generate fact families, find missing parts, partition one whole in different ways, build number bonds to 20, bridge to ten, split tens and ones, and explain their reasoning.

The editable 18-slide presentation provides explicit teaching, worked examples and guided practice for whole-class lessons. A separate editable 22-slide quiz includes 10 question-and-answer pairs using multiple-choice, true-or-false, short-answer and explanation formats. The 39-page unit plan combines colour displays, cards, mats and games with black-and-white differentiated worksheets, a two-page assessment, 12 matching red-answer pages and a five-level marking rubric.

The unit is written in Australian English for approximately five lessons, with support, core, challenge and extension opportunities across the teaching sequence.

Learning Focus

• Identify a whole and its two parts
• Combine and separate quantities
• Represent addition and subtraction with part-part-whole models
• Write and check related fact families
• Find missing parts and partition a whole in multiple ways
• Develop number bonds to 20 and bridge to ten
• Split two-digit numbers into tens and ones
• Communicate mathematical reasoning

Classroom Use

Use the presentation for explicit whole-class teaching and modelling, then reinforce concepts with the display and reference poster. The card sort, partition mats and two games support collaborative work, maths rotations and guided groups. Differentiated worksheet pages can be used for independent practice, intervention, homework or extension. Finish with the editable quiz, two-page assessment and five-level rubric.
