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?
