Provide a simple example, such as a problem involving adding apples, to show how a strip diagram is drawn and used. Encourage students to think of strip diagrams as a way to ‘see’ the problem before solving it. In the next class, we will practice creating and interpreting strip diagrams with a variety of word problems.

Drawing Strip Diagrams for Addition and Subtraction – Use strip diagrams for operations – Example: Addition strip diagram – If Sam has 3 apples and gets 5 more, how many now? – Example: Subtraction strip diagram – If Lisa has 10 candies and gives 4 away, how many left? – Solving multi-step problems | This slide introduces students to the concept of using strip diagrams as a visual tool to solve addition and subtraction problems. Start by explaining that strip diagrams are like bar models that can represent numbers and their relationships. For the addition example, show how to represent Sam’s initial 3 apples and the 5 he receives later in a diagram, and then combine them to find the total. For subtraction, illustrate Lisa’s 10 candies and how we take away 4 to find the remaining amount. Emphasize that these diagrams help to visualize the problem, making it easier to understand and solve multi-step word problems. Encourage students to draw their own strip diagrams for other problems and share their solutions.

Strip Diagrams: Multiplication & Division – Example: Multiplication strip diagram – Visualize groups of items being combined – Example: Division strip diagram – Shows how a total is split into equal parts – Compare diagrams for operations – Notice patterns between multiplication and division diagrams – Practice with class activity | This slide introduces students to the concept of using strip diagrams as a visual tool to solve multiplication and division word problems. Start by explaining that a multiplication strip diagram represents groups of items being combined together. Show an example with simple numbers, such as 3 groups of 4 items. Then, move on to a division strip diagram, which illustrates how a total number is divided into equal parts, for example, 12 items split into 3 groups. Highlight the relationship between multiplication and division, showing how these operations are inverse of each other using strip diagrams. Conclude with a class activity where students draw their own strip diagrams for given multiplication and division problems to reinforce their understanding.

Solving Multi-Step Problems with Strip Diagrams – Break down the problem into steps – Understand the question and divide it into parts – Create a strip diagram for each step – Draw a bar to represent each part of the problem – Solve the problem step by step – Use the diagrams to find the solution, one step at a time | This slide introduces students to the concept of solving complex word problems by breaking them down into manageable steps.
