## Units of length

• Year group: Year 2
• Term: Spring
• Topic: Length, weight and volume
• Duration: 1 weeks
• Keystage: KS1
• Age Range: 6 to 7 yrs
• Unit can be taught out of sequence: Y
• Week Range: 11

In this chapter, pupils measure lengths and heights in metres (m) and centimetres (cm) using rulers.

Pupils build on previous learning by using standard equipment and units to measure lengths and heights. They use the standard measurements of metres (m) and centimetres (cm) and measure to the nearest unit. They choose the most appropriate unit to estimate and measure a given length or height in any direction.

As before, pupils use common language to compare lengths and heights and start to put them in order. First introduced in the place value chapters, pupils use symbols such as < , > and = to form comparison statements (eg, 1m > 1cm).

## Resources for this topic

### White Rose Maths

#### Reasoning - Problem Solving - Money Problems (KS1/2) - March 17th

Tow more problems for KS1 and two for KS2.

In KS1 children have to use the information to complete a pictogram and then work out the length of a lolly and car.

At KS2 children need to understand what a bar chart is showing and use this to work out a total. Q2 requires children to find the mean and then given the mean find the height of another horse. There is also some converting between measures thrown in to make it extra challenging.

Every day in March the White Rose Maths Hub is aiming to put out a question of the day.

Tweet us @WRMathsHub a picture of your children's answers for a chance to win a prize.

#### Length

### Mathematics Mastery

#### Units of length

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of units of length.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Like what you see? Mathematics Mastery is a professional development programme for teachers with a mission to transform mathematics education in the UK.

This task is just a taster of the complete classroom resources we offer. We also provide in-depth development training, online CPD, specialist support and assessment tools.

We believe all elements of our programme are vital in creating lasting change – enabling every child to enjoy and succeed in mathematics.

#### Year 2 - Measurement - Length and Height - Week 11 - Spring - Block 5 - White Rose

This pack covers Year 2 - Measurement: Length and height (Block 5 - week 11).

It covers the small steps:

• Measure length (cm)
• Measure length (m)
• Compare lengths
• Order lengths
• Four operations with lengths

The resources in this pack listed below include worksheets and activities along with answers for each pack:

• Worksheets - Measure length (cm)
• Worksheets - Measure length (m)
• Activity - Sorting cards - Smaller/ bigger than a metre
• Worksheets -Compare lengths
• Worksheets -Order lengths
• Worksheets -Four operations with lengths
• Board Game -Operations with lengths
• Contextual planning sheet for the block

IMPORTANT: PDF format - must set print option to fit to ensure accurate scaling regarding packs that require children to measure lengths with a ruler.

The resources support a mastery approach to encourage a deeper understanding of the topics taught. It follows a CPA (Concrete, Pictorial, Abstract) approach to ensure all children can access learning. The pack provides pictorial and abstract representations, along with reasoning, problem solving and open-ended investigations. Details of this can be seen in the contextual overview provided.

I hope you find them useful. If you have any questions, please email primarystarseducation@gmail.com.

Thanks,

Primary Stars Education

#### Y3 - mm, cm, m, km

From 1cm/10mm to 7km, these slides show equivalent units that children sitting with rulers can relate to, well to start with...

#### Maths Primary: Measuring/Shapes 'Straws 2'

Straws contains 10 activities to develop thinking skills and facts for shape at KS1, KS2 and KS3. Straws 2 adds another 4 activities, to include symmetry, perimeter and nets. Simple ideas and a great range of activities lead to real exploration of properties of 2-D shapes, and more.

#### Science investigation into sizes of hands and feet

KS1 investigation comparing sizes of hands and feet

#### Shape & Space patio investigation

A lesson resource pack based on a real life problem about building a patio. (Actually based on my own patio!). To be delivered over 1 or several lessons. Differentiated activitiy sheets to suit Year 4 - 6. Topics also included: using and applying numbers; multi-step problems.

#### Area and Perimeter

This is a lesson I taught and was graded outstanding. Cards were differentiated for lower ability. I have a Y5 class but it could be used in Y4 or Y6. Hope it's of use to someone. Questions have come from various resources so thankyou.

#### Maths Functional Skills: A New Floor worksheet

Students are to work the area and perimeter of floor plans in order to work out the cost of laminate flooring.

#### KS2 (7-11 year olds) Quiz (Area and Perimeter)

General 'Area and Perimeter'&' quiz which includes measuring area, measuring the area of a rectangle and solving word problems involving area. This quiz is to use as an aid to see if pupils have understood the concept of &';Area and Perimeter'. Hope you find it useful.

#### Perimeter and Area 2 - Worded Problems

This pack includes one question with a full worked example, a worksheet for pupils and an answer sheet.

More problems and activities like this can be found at www.boommaths.com.

This problem is catagorised as 'Little Tricky' [suitable for KS2 and KS3].

In addition to the problem there is a Thinking Skills section, Getting Started tips and a full worked example.

A fabulous maths resource for teaching Perimeter in a more 'interesting' and advanced way.
