# Problem Solving Strategies Lesson Plan: Make an Organized List

### Submitted by: Jessica Dozier

In this lesson plan, which is adaptable for grades K-3 , students use BrainPOP Jr. resources to make organized lists to solve problems. Students will apply their understandings to real-world situations involving plane shapes.

### Students will:

1. Make organized lists to solve problems

### Materials:

• Visual learning video
• Projector and computer
• Pattern blocks (10 green triangles, 5 blue rhombuses 1 yellow hexagon)
• Worksheet pages 223-225
• Computer and internet access for BrainPOP

### Preparation:

Be sure that students have already used pattern blocks to create shapes. They should have also already learned how to name and describe shapes.

### Lesson Procedure:

1. Ask students if there are any other ways to make this shape using the yellow hexagon block. Then tell the students that they can now use the blue rhombus shape to create the given shape. Ask the students how many blue rhombus blocks fit together to create the give shape. Record the answer on the given chart and ask the students to do the same.
2. Demonstrate using the magnetized pattern blocks how the two green triangle shapes will fit with the yellow hexagon shape to create the given shape. Then show the students how to complete the first way written on the given chart.
3. Have students work with a partner to find all the ways to make a shape shown in their textbook or one that you have created/displayed for them to see (you can use one of the shapes from the Activity page if desired.) Monitor the students as they work.
4. Ask one or two students to share the way they created the shape. Have students use their pattern blocks as you uses the magnetized blocks to demonstrate all possible answers. Start by using the largest block (yellow hexagon) to see if it fits inside the shape. Then try the blue block because it is the next largest. Ask the students if the blue rhombus block will fit into the shape with the yellow hexagon block. Next, ask the students if the green triangle block will fit into the shape with the yellow hexagon block. Ask the students how many green triangle blocks will fit into the shape.
5. Pass out pattern blocks, and give students one minute to play/build with them. Then tell students to place blocks on their name tags and to leave them there until you tell you to move them.
6. Play the Plane Shapes video for the class and discuss what students learned.
7. Help students recall what they have learned about naming and describing shapes in past lessons. Tell students that they will be learning how to make an organized list to show all of the different ways to make larger shapes combining pattern blocks.
8. Have students complete the rest of the chart with their partner.

### Extension Activity:

When students finish their work they can create their own shapes using the pattern blocks that they have on their desk.
