Gingerbread Men

TaskGina is making six gingerbread men. Gina needs raisins for each gingerbread mans eyes. How many raisins does Gina need to make six gingerbread men? Show and tell how you know.

TEKS Unit of Study and Evidence

Counting and Cardinality UnitThe Counting and Cardinality Unit involves understanding numbers and how they are used to name quantities and to answer questions, such as:

How many balls is the clown juggling? Do you have enough cups for each member of your group to have one?

Exemplars Task-Specific EvidenceThis task requires students to combine, count on and have number sense to 12. It also requires students to recognize that a gingerbread man has two eyes.

Underlying Mathematical Concepts Number sense to 12 2 to 1 (2 raisins to 1 gingerbread man) Addition/Counting on Patterns

Possible Problem-Solving Strategies Model (manipulatives) Diagram/Key Table Tally chart Equation

Possible Mathematical Vocabulary/Symbolic Representation (cont.) Pair Total/Sum Double Sets Pattern Dozen Odd/Even

Possible SolutionsGina needs 12 raisins.

Possible ConnectionsBelow are some examples of mathematical connections. Your students may discover some that are not on this list.

Eyes are pairs. Patterns: Raisins +2, Gingerbread man +1. 12 raisins are a dozen. 6 is half of 12. One gingerbread man has 2 eyes. Student adds more gingerbread men/eyes to extend the task. Double the number of gingerbread men to get the total number of raisins. There is always an even number of raisins used. If Gina made noses, she would need six more raisins.

Novice Scoring Rationales, Student 1

Criteria and Performance Level

Assessment Rationales

Problem SolvingNovice

The students strategy of drawing only one gingerbread man and himself does not work to solve the problem.

Reasoning ProofNovice

The students solution does not demonstrate understanding of the underlying mathematics of the problem. The student does not indicate Ginas six gingerbread men and a total of 12 raisins for eyes.

CommunicationNovice

The student is not given credit for the mathematical term diagram. The student is drawing a picture of his gingerbread man and himself. The scribing supports that the student is not addressing Ginas six gingerbread men.

ConnectionsNovice

The student does not include a connection in her/his solution.

RepresentationNovice

The student does not provide any representation to support the underlying mathematics in the problem.
