Do you have a ton of those tiny erasers in your classroom? Do you have a difficult time walking by those little bags of tiny erasers? I know that I do. So I made up this center activity to use at the beginning of the school year. You make a bag of erasers for each student at this center. The bag should have 4 different kinds of erasers. The student will take the bag, sort the erasers into the 4 circles. Then, he/she will count the erasers and write the number on the line in the middle of the circle. You can differentiate this activity by having the students color the circle that has the most erasers or color the circle that has the least erasers.
K.CC.3. Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
K.CC.4. Understand the relationship between numbers and quantities; connect counting to cardinality.
K.CC.5. Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
