Sorting Even and Odd, M 401

[Alice Gabbard]

v.1 Take a handful of cubes, count them and see if you can make pairs with them, using as many as you can. Write the number on the chart under the word "Even." If you have one cube left over, write the number under the word "Odd." Repeat the activity with all the different numbers of cubes from 1-20.

v.2 Build and keep all pairs of snap cubes for even numbers: 2, 4, 6, 8, 10, 12...20. Look for patterns; write what you notice. Build and keep all pairs plus one for odd numbers: 1, 3, 5, 7, 9...19. Look for patterns; write about what you notice.

v.3 Ask your partner to put out any number of cowboy counters in a row and cover the feet with a card while you hide your eyes. Looking at the faces of the cowboy counters, find the number of cowboy boots they are wearing altogether. Repeat for different numbers of cowboys.
v.4 Ask your partner to put out a secret number of cowboy counters and cover them entirely while you hide your eyes. Ask your partner to give you a quick peak and then tell you how many cowboy counters are under the cover. Imagine the cowboys and tell how many boots they have altogether. Repeat for different numbers of cowboys. http://www.kymath.org/intervention/doc/numeracyproject/M301-3_M301-4Cowboys.docx

I haven't done this before I think this will be good for my 3rd graders to introduce them to multiplication.
