Sketch
Pad

Draw the relationship you want to see

A sketch pad does not supply a fixed mathematical model. The learner chooses what the marks represent. That makes it useful for moving from a story to a diagram: dots can stand for objects, a line can show distance, and rectangles can show groups or parts of a whole.

Before calculating, ask what each mark means. In a drawing of four groups of three, a group might represent one plate and a dot one cracker. The same twelve dots could represent a different situation, so the explanation matters as much as the picture.

Keep the drawing simple enough to discuss

Use a few clear marks rather than spending the lesson on decoration. Color can distinguish two parts of a total, but labels should make the meaning understandable without relying on color alone. Draw an arrow, circle a group, or add a short note when it helps someone follow the reasoning.

A rough sketch may show a relationship without preserving exact lengths or angles. If a question depends on measurement, use an agreed scale or a more structured tool, such as a number line, math bars, or geometric pieces.

Paper, a small whiteboard, and a digital sketch pad all offer ways to make and revise a model. Keep useful work long enough to discuss it before erasing. The goal is a picture that supports an explanation, not a polished drawing.
