Presentation Transcript

  1. Use Model Drawing in Four-Step Process Step 2 Step 1 • Main Idea of Question Details Step 3 Step 4 • Work the computation (s). • Describe how the problem was solved.

  2. Four Step Process Model Drawing • Main Idea • Read the problem. • Write the main idea in the question. • Details • Write who the problem is about (related to main idea.) • Write what the problem is about (related to main idea.) • Draw unit bars of equal length. • Re-read the problem one sentence at a time adjusting the unit bars to match the story and identify the question on the model. • Strategy • Work the computation (s). • How • Describe how the problem was solved.

  3. Extra Information • If a child understands that the details are what is needed to answer the main idea of the question, he will NOT include the extra information in the details. • Try to keep students focused on what the question is asking them to find. • However, if the child includes the extra information in the drawing, placing the ? in the model will help them understand that the extra information is NOT needed.
