Gingerbread Men

TaskGina is making six gingerbread men. Gina needs raisins for each gingerbread man’s 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 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.• Youcancountbytwostofindthenumberofraisineyes.

Criteria and Performance Level

Assessment Rationales

Problem SolvingNovice

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

Reasoning ProofNovice

The student’s solution does not demonstrate understanding of the underlying mathematics of the problem. The student does not indicate Gina’s 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 Gina’s 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.

Expert Scoring Rationales



Problem SolvingExpert

The student’s strategy of making a diagram of six ginger-bread men and 12 raisins for eyes works to solve the prob-lem. The student indicates a correct answer, “12.” The stu-dent then uses an alternative strategy of a table to show the six gingerbread men and 12 raisins for eyes. The student relates this problem to a previous, completed problem.

Reasoning ProofExpert

The student creates a table to verify her/his answer of twelve raisins. The student also relates the problem to a previous, completed problem and links the mathematical similarities.

CommunicationExpert

The student correctly uses the mathematical terms diagram, key, dozen, pair, table, pattern.

ConnectionsExpert

The student makes the mathematically relevant Practitioner observations, “Pair of eyes,” “Dozen is 12.” The student states “2 raisins is a pair,” and “I did the add 2 pattern.” The student also recreates the problem by adding her/his own gingerbread man for a total of “14,” and states, “I did one for me. Now it is 14 raisins.” The student makes an Expert connection by verifying her/his own answer by creating a table and stating, “This is called correct because I got 12 again.” The student makes an additional Expert connection by relating the Gingerbread Man problem to a problem done in the past that involved counting dog legs. “We did that when we counted 3 dogs legs. That table was hard because I did 4, 8, 12 on it.”

RepresentationExpert

The student’s diagram is appropriate and accurate. The key and the scribings provide all necessary labels. The student’s table is appropriate and accurate with all necessary labels included.
