Teaching and response guide
- Begin with: Read this pencil length from the ruler.
- Connect the response to: Pencils A and C are placed end to end. What is their total length?
- Ask students to apply the idea: Draw a bar graph of the three lengths. Label each bar and use one centimeter per step.
Watch for: Check the meaning of each quantity, the operation and the units; a numerical answer alone does not show the full reasoning.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
