Materials

 BLM of animals cut into cards

Task

Cut out the animal cards and mix them up.  Show the student the animal cards.  Say: How could you organize the cards into groups?  After the student responds, say:  Put the cards into groups.  Once the cards are sorted, ask the student:

●     Compare your groups.  What do you notice about each of your groups?  Prompt if needed: Is there anything that is the same about your categories?  Different?

●     Then ask: How many more cats are there than dogs?  How many more dogs would you need to have the same amount as birds?

Continuum of Understanding

Not Yet Proficient

·         Unable to identify a way to organize the cards independently

❑    Sorts and classifies cards into categories.

❑    Identifies “most”

❑    Identifies “least”.

❑    Correctly solves “how many more” questions.

Progressing

·         Identifies a way to organize the cards, but inconsistently sorts as indicated

·         Changes the category(ies) during the organization process

·         Sorts the cards but does not compare the groups, even after prompting

·         Solves one or more “how many more” questions incorrectly

Meets Expectations

·         Identifies a way to organize the cards and sorts them correctly as indicated

·         Compares the groups accurately, identifying such features as most, least, same

·         Solves all “how many more” questions correctly
