Introduction to the Bar Model Addition and Subtraction Miss Bishell-Wells

We use bars to help us visualise a problem We use bars to help us visualise a problem. To begin with we are going to look at some simple examples together. 19 + 7 Try: Method Calculation ? 19 + 7 = 26 19 7

19 + ? = 28 Method Calculation Try: 28 28 - 19 = 9 19 ?

There are 32 children in Year 4 and 33 in Year 5. How many children are there in Years 4 and 5 ? Method Calculation Try: ? 32 + 33 = 65 32 33 Year 4 Year 5

There were 423 people on Train A, 298 people on Train B and 196 people on Train C. How many people were there altogether ? Method Calculation Try: ? 423 + 298 + 196 423 298 196 423 + 298 = 721 Train A Train B Train C 721 + 196 = 917

Try: ? There were 341 people on the school trip from two different schools. There were 276 people from one school. How many people were from the other school ? Method Calculation Try: 341 341 - 276 = 65 276 ?

Try: There were 56 children in the music lesson, but 5 went to the toilet and 3 were sent home because they were ill. How many children were left in the lesson? Method Calculation Try: 56 5 + 3 = 8 56 - 8 = 48 5 3 Toilet Ill ? 8 5 3

Now try these The attendances at three football matches were 45 674, 49 128 and 38 763. What is the total attendance for the three games? 674, 128 and 763. There were 23 491 people at the pop concert (in Stands A,B and C). In Stand A there was 13 432 and in Stand B there were 7 652 people. How many people were in Stand C? There were 2491 people at the pop concert (in Stands A,B and C). In Stand A there was 432 and in Stand B there were 652 people. How many people were in Stand C?
