The MyStemKits.com K – 1 Measurement and Data Lessons consist of a complete set of lessons aligned to the Common Core State Standards (CCSS) for mathematics. This comprehensive set of lessons addresses the entire measurement and data domain for kindergarten and addresses many of the measurement and data standards for first grade as well.
The kits developed for these lessons include the following:
Students explore the measureable attributes of a variety of objects. Attributes include continuous variables such as weight, length, and volume, as well as discrete variables such as the number of arms on a starfish or rungs on a ladder.
Students directly compare two objects with a measurable attribute in common to decide which has more or less of the attribute. They are introduced to comparison terms (e.g., longer and more) and use these terms to describe their conclusions.
Students are introduced to the concept of a right angle. They identify examples of right angles in the real world and in geometric shapes and are introduced to vocabulary related to angles (i.e., sides and vertices). This lesson prepares students for understanding and identifying rectangles.
Students continue to measure lengths using an unspecified unit describing lengths numerically. In addition, they compare lengths of objects by both physical side-by-side comparisons and numerical comparisons.
Students classify objects based on a discretely measure attribute (e.g., the number of arms of a starfish). They sort categories by count, and count the number of objects in each category.
Students classify objects based on a continuously measured attribute (e.g., the length of a caterpillar). They measure each object using a previously introduced unspecified unit and sort the objects into categories according to length. They sort categories by count, and count the number of objects in each category.
This curriculum track is still in development. The following lessons address many of the standards in measurement and data required for first grade, but do not address time and money. Lessons on those subject-matters will be added in the future.
Students review direct length comparisons as they directly compare the lengths of two objects and use the terms longer, shorter, and equal to describe their conclusions.
Students directly compare the lengths of three objects and order them by length. Then they indirectly compare the lengths of two objects using a third object.
Students review the concept of length measure by using multiple copies of an unspecified length unit to measure the lengths of a number of items. They compare the lengths of three objects numerically and order the objects according to their lengths.
Students transition from measuring length using an unspecified unit to measuring length in inches using a specially designed ruler marked off in one-inch intervals with no scale given (the no scale/one-inch ruler from the MyStemKits.com Measuring with Length Units Kit). They use this ruler to measure the lengths of a variety of objects and express the lengths numerically in inches.
Students transition from using the no scale/one-inch ruler from the MyStemKits.com Measuring with Length Units kit to using a conventional ruler. They practice using the conventional ruler to measure the lengths of objects both in the real-world and on paper.
Students classify objects based on a discretely measured attribute. They organize their classifications and represent them in a graph. They ask and answer questions about the total number of data points, the number of data points in each category, and the differences in the number of data points across categories.
Students classify objects based on a continuously measured attribute (e.g., the length of a caterpillar). They organize their classifications and represent them in a graph. They ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
