Within some time period whichis much too short for them to do the computations, students are asked to choose the most reasonable answer from each set of four. 7. Apply estimation in working with quantities, measurement, time, computation, and problem solving. Students have small pieces of yarn of slightly different lengths ranging from 2 to 6 inches. Then they use their individual pieces to measure other objects in the room. Each child is responsible for estimating the lengths in terms of his or her own yarn, but they can use evidence from other children's measuring to help make their own estimates.
Students regularly estimate in situations involving classroom routines.
For example, at snack time, they may guess how many cups can be filled by each can of juice or how many crackers each student will get if all of the crackers in the box are given out. Kindergartners always have fun deciding which color is best represented in a group of multi-colored objects. After everyone has committed to a guess, the children can sort the objects and count each color. They can then make bar graphs to show the distribution of the different colors. For example, on one page, three vases are shown filled with three different kinds of flowers.
