These activity/task cards relate to the skills taught in 2nd Grade Envision Math Topic 12. For the first activity (12-1), students will determine if a shape has been divided into halves, thirds, or fourths. In the second activity (12-2), students record the unit fraction for the shaded part of each shape shown on the cards. For the third activity (12-3), students also record fractions of a whole indicated on a card. These cards differ from the 12-2 activity in that there are multiple parts shaded indicating a numerator greater than 1. There is no activity to correlate to 12-4, estimating fractions. For the fourth activity (12-5), students indicate the fraction for a set. The fifth and final activity (12-6) involves problem solving to determine the amount when given a fraction of a set. There are recording sheets and answer keys for each activity. These activity/task cards can be used in a math center, for a scoot game, or as a whole group activity. For a whole group activity, place the cards in various areas throughout the room and allow students to search and record.
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
