Take away and explain

Learning goal

Represent subtraction and connect start, change, and result to an equation.

Before teaching

Can count the start set and recognize its total; understands the story vocabulary.

Model

Place 5 counters: “Five birds are here.” Move 2 off the mat: “Two fly away.” Count the 3 remaining. Write 5 - 2 = 3 and point to the start, removed part, and result. Explain that the minus sign records taking away in this story.

Guide, then apply

Act, draw, and explain the pupil stories. Cross out or move only the removed objects; keep enough of the record to show the starting set. Include removing none and removing all. Use mental relationships after concrete understanding, not as a replacement for it.

Interpret the response

Practice results: 4 - 1 = 3; 5 - 3 = 2; 3 - 0 = 3; 2 - 2 = 0. If the child counts removed objects as the result, label “left here” and “went away,” then retell the story.

Support

Use a smaller understood start set, gesture, or an adult scribe. Let the child direct the physical action. Record representation independently from numeral writing.

Extend when ready

Use the pupil kindergarten stories within 10 under K.OA.2. Develop fluent facts within 5 under K.OA.5 through understood relationships. Neither is a required TK percentile cutoff.

Fresh check

Tell “Four toy cars were parked. Two drove away.” Ask how many remain, request a new model, and ask where each equation number appears in the story. Later change context and starting quantity.
