## Perimeter and area

• Year group: Year 5
• Term: Autumn
• Topic: Length, weight and volume
• Duration: 2 weeks
• Keystage: KS2
• Age Range: 9 to 10 yrs
• Unit can be taught out of sequence: Y
• Week Range: 10 - 11

In this chapter, pupils calculate the area of rectangles (including squares) and solve problems that involve measures.

Pupils reinforce work on perimeter and area by measuring and calculating the perimeter of composite rectilinear shapes. They calculate and compare the area of rectangles (including squares) using square centimetres (cm²) and square metres (m²) and estimate the area of irregular shapes.

Using existing knowledge from previous chapters and other topics, pupils solve problems involving length and area with all four operations. These problems may involve decimal notation and scaling.

### White Rose Maths

#### KS2 - Problem Solving and Reasoning Questions

Here are a final few problem solving and reasoning problems ahead of SATS this week. Feel free to use them,

@WRMathsHub

#### Reasoning - Problem Solving - Mixed Problems - March 18th

Friday's questions. There are two problems for KS1 and two for KS2.

In KS1 problem children solve number problems. Encourage students to use a bar model or other diagram for Q2.

At KS2 children have a number problem to solve (bar modelling would be good here) and also a problem involving area and perimeter of a square and rectangle.

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.

### Mathematics Mastery

#### Perimeter and area

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 concepts of perimeter and area.

• 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.

### Resources shared by teachers

#### 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 - Differentiated Word Problems

This file contains 3 sets of differentiated word problems involving area and perimeter. Ideally for Y5 or Y6, but could be used with Y4 if high ability.

#### Theme Park, Maths Enterprise

This is a group of resources I made (I used some ideas from other places, but I made the things myself) in order to use as many Maths related exercises with the final aim of creating their own theme park. Some of the skills covered are:
Shapes, co-ordinates, symmetry, speed, line graphs, pictograms, bar graphs, perimeter, area, percentages, tally, problem solving, survey, money, budget and time.

Enjoy!!

#### Area of triangles and parallelograms tutorial

This short tutorial covers area of triangles and parallelograms, explaining via area of a rectangle. Powerpoint is animated. A small selection of practice questions are provided with answers.

#### Perimeter Lesson Plan

Two part lesson on perimeter for a low ability year 9 group. They really found Perry Perimeter engaging and were given time during starter of lesson 2 to create their own cut out of Perry to help them find the perimeter. Lesson ends on a game of Snakes and Ladders (in my other shared resources) which encouraged them to practice their skills as they have low attention spans.

#### Maths Area & Perimeter of rectangles starter

Work out the Area and perimeter of a number of rectangles and then put them in order. Students should notice that large areas do not necessarily mean larger perimeters

#### 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.

Visit http://www.boommaths.com/teaching-resources/infinite-questions/ for infinite questions. Ideal for a starter or plenary.

#### Reasoning and Problem Solving Questions Collection - KS1 and KS2

These booklets each contain over 40 reasoning and problem solving questions suitable for KS1, KS2 and KS3 classes. These are the questions that we have been putting out each day in March 2016 on Twitter in the run up to SATS.

The answers are provided with some simple notes at the back of the booklet and for some problems supplementary questions and variation has been provided.

As always we welcome any feedback on the work we are doing and the materials that we are releasing.
Thank you for taking an interest in our work.
