Classify familiar plane and solid objects by common attributes, such as color, position, shapes, size, roundness, or number of corners, and explain which attributes are being used for classification.

The student will be able to sort shapes (both flat and three- dimensional) into groups. The shapes in each of these groups will all have a common attribute such as the same color, shape, size, position, roundness, or number of corners.

Sorting Rule Sensations: This skill is very easily practiced in everyday life. You can have your child practice this standard when they are cleaning their room. Ask them to sort their toys into groups and then provide a “sorting rule.” This means that your child will need to give you a specific reason for why they placed in toy in each group. Maybe they will place hot wheels cars and big trucks together. Their sorting rule may include “I put all toys with wheels together.” Maybe they will have a different group of mixed toys that are all blue. As long as they can provide a rule that accurately describe ALL toys in each group, then their rule should be accepted. If they have some toys miss sorted, discuss the rule they provided and why the toy would not fit in that rule.

Corner Caper: Out in your child’s natural environment (playing outdoors, traveling in the car, etc) ask then to identify objects that they spot, which contain a specific number of corners. Before you begin this activity, it is a good idea to review what corners are (the spot where to straight lines on a shape connect). Next, tell your child you are going to play “Corner Caper.” One person gets to pick a number of corners and the other player will need to locate an object with the number of corners that the other player determined. As the player looking for the object locates something with the correct number of corners, the roles will be switched and they will then pick the number of corners and the other player will need to locate a corresponding object. Discuss the objects that are picked and verify that the numbers of corners are correct.

Quiz Show: For this activity, you can enlist the whole family to play for a night of fun and entertainment while reinforcing this skill. You will need to have one person “host” the game and ask the contestants riddles that will be written out on index cards. Each contestant can either use their hand to tap the table or a bell. The host will read a riddle that will either describe a shape that the contestants will need to identify or the question will be related as to how to classify a certain shapes based upon color, position, shape, size, roundness, or number of corners. The first contestant to ring their bell will be allowed to attempt to answer the question. If they are correct they will receive a point. If they are incorrect the other contestants will be given an opportunity to answer the question that was missed. Whichever contestant answers correctly, they will receive a point. The contestant with the most points at the end of the game wins.

For this activity you will need a large sheet of butcher paper, a marker, glue, magazines, and scissors. Begin this activity by reviewing what it means to classify or sort an object. Next discuss different sorting rules such a grouping objects by color, size shape, position, etc. At this time, have your child determine how they would like to sort objects for that particular week. Maybe they pick “by color.” If this is the case, at the top of the butcher paper they would need to write the label “sorting by color.” Next, they can divide the paper up into 4-6 sections and inside of each section write the name of a different color. For the next week, using a different magazine each day, have your child search for pictures that are related to their color choices on the butcher paper. When they find pictures that correspond to their color words, they will need to cut out the associated picture and glue it under the correct color word. At the end of the week your child should have quite a collection of objects associated with their sorting rule of choice.

Sorting Book: Have your child create their own sorting rule book to demonstrate their understanding of this skill. Gather 8 pieces of paper and staple them together to create a book for your child. On the first page, have your child decorate the cover with the title “My Sorting Book.” On the inside of the book have your child write the following labels; (one per page) color, size, shape, roundness, number of corners, and position. After each page has been labeled, ask your child to draw a picture that would demonstrate that particular sorting rule. For example, on the page that is labeled “color,” they would need to draw objects that are all the same color. They could draw purple books, purple balls, purple lollipops, anything at all, as long as it is purple. This same theme would continue throughout the book. When drawing a picture to demonstrate each sorting rule, the student would need to stay consistent with the label on the top of each page and make sure that the pictures they draw correspond to the label at the top of each page.
