Concept: hand and eye coordination, visual-perception, large motor skills, weight discrimination, size discrimination,
1. Collect several rocks that vary in size. Have the children find rocks that are small and somewhat consistent in size. The term pebble can be introduced as a way to describe these small rocks.
2. Have the children divide the pebbles into groups of 20. Then have each set of twenty pebbles marked with one color by a sharpie marker. This will allow the students to identify their pebbles used in the activities listed below. (To save time, the teacher can simply buy 7 bags of colored stone.)
3. Create a target inside the classroom. This can be done a couple of ways.
a. Use popcorn buckets and place them in a line, each one being 1 foot away from the next.
b. Make a bulls eye on the floor with tape. The center being the most points, the outside rings being the least.
4. The goal is to toss one pebble into each contain, starting with the nearest container and working outward. Or, the goal is to get as many pebbles into the center ring as possible.
5. The children will be in small groups of about four or five and will make a line behind the first person, who is standing on a piece of tape which tells them where to stand.
6. Each child will have a small cup filled with one color of pebbles. He/She will toss one of their pebbles into the cup/target and then go to the end of the line and let the next person go.
7. If the child is tossing the pebbles into the cups, he/she may not go onto the next cup unit they are able to throw a pebble into the one before it. The game ends when time is up for each student, or when he or she put a pebble in the each of the buckets. It is not a competitive game against each other, only against oneself.
8. If the child is tossing the pebbles into the target, then he/she is just trying to get as many in the center as they can. The game is over when time runs out or they put 5 pebbles into the center bulls eye. Once again, it is not a competitive game against each other, only against oneself.
1. Have students collect both large and heavy (but not too heavy as we do not want any injuries), and some small and light. Have each child pick 6 stones; two stones being small, two stones being large, and two stones in the middle. With adult supervision, let three students at a time go outside on the playground (when no one is outside) and toss their six stones. Have the students take note as to which one went the farthest, which one was the easiest to throw, and which one was the hardest to throw. When all students have a turn, have a class discussion about what they found out.
2. Have the students do the same activity as above in number 4, but do this outside and with a much large distance between each bucket. Discuss what strategies they may have had to use in order to make some of these buckets.
