Mathematics Ages 5 - 6: Number bonds Introduction: This lesson is about developing number bonds. It uses a large visual display to engage the children’s attention. It is an open-ended, teacher-led activity to support the exploration and investigation of number bonds. Another lesson plan on this topic can be downloaded from the ictopus site. Go to Lessons2go, Materials by subject, Mathematics and 29/04/08 (Teddy’s see saw) Resources computer and an interactive whiteboard (or data projector) for whole class work the Number Bond Machines program from: http://www.amblesideprimary.com/ambleweb/mentalmaths/numberbond.html Previous learning Children should be able to: recognise numbers up to 10 add numbers to a maximum of 20 (or whatever total is chosen) count on and count back Learning Objectives To be able to develop number bonds up to 20 (or any other total) To be able to recognise the relative ‘size’ of different numbers What to do This is a straightforward lesson whereby the teacher has the class sat in front of an interactive whiteboard. The Number Bonds program will need to be downloaded from the site given above. The teacher chooses the target total (e.g. two numbers that make 12). The interactive whiteboard will display the first number and the children have to work out what the second number will be. One child could come out to the front of the class and type in their answer, or everyone could be asked to write their answer on an A4 whiteboard and hold it up; the teacher types in the most common response. Alternatively, another child could be asked to select which of the answers on offer they want to accept. The program keeps a running score so that the children can follow their progress. Differentiation Less able children may need to use counters to help discover the missing number. Although this lesson is described as a class activity, children working individually or in pairs could use the program themselves. The role of ICT ICT offers a very visual presentation. It engages the children’s interests and by using the check button the teacher is able to build up a sense of excitement and anticipation. It provides immediate feedback and the children can easily see whether or not they have been successful. Motivation is increased and the teacher is in control of the pace of the lesson. Follow-up suggestions One way to extend the use of the program is to ask the children to write down three numbers that make up a particular total. For the more able there is also a key stage 1/2 version of the program at: http://tre.ngfl.gov.uk/uploads/materials/17913/nbKS2.swf This allows much greater flexibility, covering similar work to that described above but moving on to cover inequalities, all 4 operations and negative numbers

Assessment Some children may need structural apparatus to help them whilst others may possess sufficient mental strategies. Children should be encouraged to explain how they arrived at a particular answer. How confident are they? There is sufficient scope in this program to challenge all children; the teacher’s task will be to ensure that all the children are progressing at a rate commensurate with their ability
