AGE: 8 years

DURATION: 5 periods of 40 minutes each

DATE:

SUBJECT: Mathematics

TOPIC: Geometric patterns

SPECIFIC OBJECTIVES: At the end of the lesson, the pupils should be able to

1. Create and describe simple patterns where the number, size or position of shapes in each stage changes in a predictable way.
2. Describe and create patterns where the size and shape changes in a

predictable way.

1. identify, describe, extend and develop geometric patterns.

INSTRUCTIONAL TECHNIQUES: Explanation, question and answer, demonstration, practical, assessments

INSTRUCTIONAL MATERIALS: Plastic spoons, matchsticks, etc. (bring objects from home), learners stationery or books(objects to use to make patterns), Shape cut-outs, videos from source-

PERIOD 1: Geometric patterns around us

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculationsCalculate1 3 × 10 =     2 9 × 10 =      3 0 × 10 =     4 8 × 10 =      5 4 × 10 =     6 2 × 10 =7 10 × 10 =8 5 × 10 =9 7 × 10 =10 6 × 10 = Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacher• Gives each group some matchsticks.• Asks them to use matchsticks to make a pattern with identical groups, where each grouphas only one kind of object but the position of the object in a group changes. Identicalgroups are repeated. E.g.• Uses the cups to make a pattern by using one shape or object, but having the position ofthe shape or object change in a regular way. E.g.• Use spoons to make a pattern by making groups which grow in size. E.g. CLASS ACTIVITYIn this activity learners should use their stationery to create patterns.• Asks them to duplicate the patterns that they did in Activity 1 using their stationery. Forexample they can use pens/pencils to create patterns:Identical groups are repeated. E.g. Mixed groups are repeated. E.g. The positions of the items changes. E.g. The number of items changes. E.g.• Allows them to discuss the pattern in their groups.Each group gets a chance to show and describe their patterns in words to the rest ofthe class.• Asks the learners to be judges. They are now going to choose the best pattern from allthe groups. They also have to explain why they chose that specific pattern. Pupils pay attention and participate STEP 3CLASS-WORK 1 Draw the pattern that your group made with the cups.2 Describe the pattern.3 Draw the pattern that your group made with the spoons.4 Describe your pattern.5 Design your own pattern, using triangles.6 Describe the pattern. Pupils attempt their class work STEP 4HOME-WORK Design a colourful and beautiful pattern.a You may use any shapes and colours.b Remember to extend the pattern you started with.c You may use more than one pattern in your design. Pupils attempt their class work STEP 5SUMMARY The teacher summarizes by reminding the pupils how to create patterns using shapes. She marks their class works, makes corrections where necessary and commends them positively

PERIOD 2 : Creating geometric patterns

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculationsCalculate1 400        2 500        3 150        4 250        5 550       6 2507 1008 4509 80010 200 Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacher* Draws the patterns on the board in preparation for this lesson. CLASS ACTIVITYThe teacherUse the shape cut-outs.Learners should each make a pattern using some of the cut-out shapes on their desks.• Groups discuss each of the patterns together – explain how the pattern grows.Some group members can present their pattern to the whole class (depending on howmuch time is available). Pupils pay attention and participate STEP 3CLASS-WORK NOTE: In this activity learners must also be able to explain the way in which their patternsgrow. This is an important part of the activity as it gives learners the opportunity to developtheir use of mathematical language.1 Draw a geometric pattern and describe your pattern:a Use triangles.b Use squares.c Use circles.2 Draw a geometric pattern using triangles, squares and circles.3 Describe your pattern. Pupils attempt their class work STEP 4HOME-WORK 1 Draw a geometric pattern and describe it.a Use rectangles.b Use triangles and circles. Pupils attempt their class work STEP 5SUMMARY The teacher summarizes by reminding the pupils how to describe and create patterns that involve change in colour, shape and size. She marks their class works, makes corrections where necessary and commends them positively

PERIOD 3: Exploring Geometric patterns

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculationsCalculateIf I count in 50s, give me the number before1 400  2 50  3 150  4 250  5 550  6 2507 1008 4509 500 10 200 Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacher• Draws the patterns given in the table below on your board before the lesson starts. Youwill need to refer to these drawings when you explain the different kinds of patterns.You don’t have to write the explanations – you will talk about these.• Uses the table below, which provides three different types of patterns, to teach learners how to- Identify- Describe- Extend and- Develop their own patterns.CLASS ACTIVITYThe teacher Instructs the learners:Make your own pattern with a different shape and your own colours.Describe the pattern. What will the next three shapes look like? Draw them.For example:Describe the pattern. (A square with a circle inside. The circle is at the top left, topright, bottom right.)What will the next three shapes look like? (The circle will be at the bottom left, thentop left, then top right.)Draw them. Pupils pay attention and participate STEP 3CLASS-WORK 2 Use any of these shapes to make two different patterns. Describe your patterns.You don’t have to use all the shapes in your two patterns. Pupils attempt their class work STEP 4HOME-WORK 1 Design and draw your own pattern using circles, squares and triangles.2 Describe the pattern. Pupils attempt their class work STEP 5SUMMARY The teacher summarizes by reminding the pupils how to extend and develop patterns. She marks their class works, makes corrections where necessary and commends them positively

PERIOD 4: Assessments

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1ORALASSESSMENTS The teacher asks questions on geometric patterns Pupils respond and participate STEP 2DISCUSSION The teacher discusses all the methods used by some learners in the oral assessments(some of the questions are solved on the board by the learners) and addresses any misconceptions that may have risen Pupils pay attention and participate STEP 3WRITTEN ASSESSMENTS 1. Draw the next shape in this pattern: 2 Draw and extend a pattern in which the sizes of the shapes increase.Learners’ answers will vary. 3 Make your own pattern using circles and squares. 4 Use three squares to draw a pattern. The size of the squares need to change in a regular way. Pupils attempt their class work STEP 4SUMMARY The teacher marks the written assessments, corrects were necessary and commends the pupils

PERIOD 5: Weekly Test/consolidations

TEACHER’S ACTIVITY: The teacher revises all the concepts treated from period 1-4 and gives the pupils follow through exercises, quiz and tests . She marks the exercises, makes corrections and commends the pupils positively.

PUPIL’S ACTIVITY: The pupils work on the worksheets and exercises given by the teacher individually

CONSOLIDATION

1 Extend the following pattern:

1. Describe this pattern.

1. Create a pattern using circles that increase in size

4 Create a pattern with 3 squares. The squares should decrease in size.
