Make teaching Fractions as Collections (Non-Unit Thirds) simple with this ready-to-use Year 4 lesson.

Students learn how to represent and partition collections into equal groups and understand non-unit fractions as part of a whole collection. The key concept focus is grouping, sharing, and representing thirds in practical contexts.

This structured lesson supports students to develop a deep understanding of how collections can be divided into equal parts, including when remainders occur and how these can be represented using equations and visual models.

What’s included:

• Lesson slides (with learning intention & success criteria)
• Teacher guidance and lesson notes
• Differentiated task cards (3 levels)
• Anchor chart (A3 printable)
• Student scaffold (number line support and visual grouping tools)
• Intervention support resource

Why teachers love it:

✔ Ready-to-teach lesson structure

✔ Print & go resources

✔ Clear progression of skills

✔ Differentiation built in

✔ Includes targeted intervention support

✔ Saves planning time

Please note:

• PDF format (non-editable)
• This is Lesson 1 of Unit 2 in a 5-lesson Unit sequence on fractions as numbers on a number line. Students begin with hands-on manipulation of collections to build a strong visual understanding of equal parts before moving into formal fraction representations in later lessons.
• Each lesson follows the same structured format for consistency and ease of teaching
