INTRODUCING THE LESSON Engagement: Prism who am I? Sit students in a circle on the carpet. Have a range of 3D shapes in the middle of the circle and read out each of the ‘What am I?’ questions (see sheet attached). As each one is read have the students guess which prism you are describing. A range of different 3D shapes A copy of the ‘What am I?’ questions 10 mins DEVELOPING THE LESSON Describing 3D shapes Extension Challenge Activity Hand a copy of the ‘Describing 3D shapes’ sheet to each student (see attachment). Students are to complete the properties table by naming and describing each shape, including its number of faces, number of edges and number of vertices. Students are then asked to identify the 3-D shape each picture (i.e. brick, can of baked beans, tent) represents and describe the properties of each 3-D shape. If students have completed the worksheet ask them to find 10 examples of 3-D shapes around the classroom and name and draw these in their maths book. ‘Describing 3-D shapes’ worksheet for each student 35 mins CONCLUDING THE LESSON Instruct students to cut and glue sheets in their maths book. Move to next lesson. 5 mins Lesson 1 Outline: Lesson 2 Outline: Activity Action Resources Time Reference INTRODUCING THE LESSON Ask students to complete ‘Describing 3-D shapes’ worksheet from previous lesson. Those students who have finished can continue with the Extension Challenge Activity 10 mins DEVELOPING THE LESSON Have a collection of empty packages of products sold in supermarkets. Have as many different shapes as you can. Study the shapes of the packages. Discuss with the students, what is the product designed to hold? Why is the package shaped this way? As a class, classify all the packages according to their shapes. Make a graph to show the number of packages in each category. Ask the students to consider which is the most common packaging shape in the class collection and why is this so? Explain to students that they are to design and construct a package for a new product soon to be released in the supermarkets. Ask students to consider which 3-D shape would be the most appropriate for packaging their product. Recording sheet & playing sheet for each pair of students 30 mins
CONCLUDING THE LESSON If students complete their packages allow them to display them to the rest of the class. Unfinished packages to be completed for homework before next week’s lesson. 5 mins Lesson 3 Outline Activity Action Resources Time Reference INTRODUCING THE LESSON Engagement: Pyramids Who am I? Sit students in a circle on the carpet. Have a range of 3-D pyramids in the middle of the circle and read out each of the ‘What am I?’ questions (see sheet attached). As each one is read have the students guess which pyramid you are describing. Complete a properties table on the board as you do this. DEVELOPING THE LESSON Hand each student a copy of the ‘Pyramids’ worksheet (see attachment). Students are to complete the properties table by naming and describing each pyramid, including its number of faces, number of edges and number of vertices. Students are then asked to draw models of pyramids using certain shapes and then draw the cross-section of each pyramid if each were to be cut horizontally. If students have completed the worksheet ask them to make one of the 3-D pyramids using straws and modelling clay. CONCLUDING THE LESSON Learning Log Instruct students to cut and glue sheets in their maths book. Move to next lesson. 5 mins Lesson 4 Outline (Assessment of topic) Activity Action Resources Time Reference INTRODUCING THE LESSON Hand students a copy of the assessment task (see test attached). Quickly go through the test, highlighting any difficulties or areas that may cause confusion. Ask if students have any questions before beginning the test. 5 mins DEVELOPING THE LESSO Allow students 30 minutes to complete the test, clarifying any questions as they arise. Have an extra activity prepared for those students who finish early. 30 mins CONCLUDING THE LESSON Learning Log Collect each students test and compile results for recording in the assessment folder. 5 mins
