1. Sort and Classify Math and Science Games Gail Gerdemann 2009

2. Same and Different  Choose two objects from the collection  Work with a partner  Name as many ways as you can that the two objects are different (your partner tallies your answers)  Name as many ways as you can that the two objects are the same  Now it’s your partner’s turn

3. Same and Different

4. Two Shells Compared Same  White  Shells  bumpy Different  Size  Shape

5. My Special Peanut  Pass out one item from a collection to each student  Tell students to get to know their special object  Write observations and make a scientific drawing of your special object  Return all objects to the collection  Find your own special object back by using your notes and drawing

6. My Special Peanut

7. Peanut Observation  Two bumps about the same size  One bump is fatter and the other is slimmer  Medium tan color – not the lightest of the group nor the darkest

8. Guess My Object  Two students share a small collection  Without touching the objects, choose one object from the collection  Describe the object so well that your partner can find it  Take turns describing and guessing  Remember: The best player is the one who makes it easy for his/her partner to find the object you are thinking about!

9. Guess My Object

10. Clues for Guess My Object  Reddish-brown  Lots of tiny holes on the surface  Shaped like a rounded diamond  A few specks of white

11. Guess My Object

12. Guess My Sort  Decide on a category for sorting a collection  Silently put objects in groups following your secret plan  When someone thinks they know your secret, allow them to try to correctly place the next object  After sorting all the objects, see if anyone can name the attributes for each group

13. Guess My Sort

14. No lobes lobed

15. What Doesn’t Belong?  Put out 4 or 5 objects from a collection or from different collections  Ask, What doesn’t belong? Why not?  See if you can find a valid reason for each of the objects to be the one that doesn’t belong by choosing different attributes for sorting

16. What Doesn’t Belong?

17. large small

18. What Doesn’t Belong? Multi-colored One color

19. What Doesn’t Belong? man-made from Nature

20. What Doesn’t Belong? heavy lightweight

21. Advanced Guess My Sort  Play the same way as Guess My Sort  Choose an attribute that requires 3 or more groups when sorting  OR Choose an attribute that have overlapping groups (use a Venn diagram)  Try sorting the same collection another way

22. Advanced Guess My Sort

23. dark light Light and dark

24. Double Trouble  Play like Guess My Sort  Choose two attributes to sort by at the same time  Example: roughness and light/dark color  Sorting groups are: rough and light rough and dark smooth and light smooth and dark

25. Double Trouble

26. Small No lobes Large has lobes Large no lobes Small Has lobes

27. Guess My Seriation  Choose an attribute that can be ordered (length, weight, color, texture)  Line up a few objects from the collection in order by the attribute (from shorter to longest, for example)  Leave lots of space between objects  Your partner tries to place the remaining objects in the right position in the seriation and state the rule

28. Guess My Seriation

29. smooth rough

30. Guess My Seriation #2

31. light dark

32. Measuring Sequence To develop understanding about the nature of units in measurement:  Use a natural objects as the unit- measure (peanuts, seeds, etc.)  Use manufactured objects as the unit- measure (math manipulatives, e.g.)  Use standard measurement tools and units (i.e. ruler in inches)

33. Measuring with Peanuts

34.  Answer 8 or 9 peanuts  Would you get the same answer if you used different peanuts?  Would someone who couldn ‘t see the book know how big it is if you tell them how many peanuts long it is?  What’s the problem with peanuts?

35. Measuring with Tiles

37. Measuring with Inches
