Year 1 Weight and Mass Lesson Pack

Teach measuring, comparing and solving problems with mass using this Year 1 weight and mass lesson pack. Perfect for spring term measurement lessons, this complete resource pack helps pupils explore heavy and light, compare objects on balance scales, and measure mass using non-standard units such as cubes and lolly sticks.

Across the week, pupils learn how a balance scale works, how to describe what the scales show using comparison sentences, and how to record measurements accurately. They then move on to measuring mass using equal units (rather than mixing units), before tackling reasoning and problem-solving questions that involve adding and subtracting mass and finding the difference between two weights.

Small steps covered

• Introduce weight and mass
• Measure mass using non-standard units
• Compare mass (heavier than, lighter than, equal to)
• Solve problems with weight and mass (adding and subtracting)

What’s included?

• Detailed lesson planning linked to the White Rose small steps
• Teaching slides introducing weight, mass, heavy and light
• Balance scale activities and comparison sentence tasks (heavier, lighter and equal)
• Differentiated worksheets for comparing mass and describing balances
• Measuring mass worksheets using non-standard units such as cubes and lolly sticks
• Reasoning and problem-solving worksheets involving adding and subtracting mass
• Challenge tasks to deepen understanding, including true/false reasoning and ordering from lightest to heaviest

This Year 1 measurement pack is ideal if you are looking for Year 1 mass worksheets, heavier and lighter activities, or practical balance scale maths resources that link directly to the National Curriculum. It supports whole-class teaching, small group work and catch-up, while giving pupils lots of hands-on opportunities to explore how weight and mass can be measured and compared.
