Measuring mass and weight (age 4+)
PROCEDURALCompare two objects directly by mass or weight and describe the difference using language such as heavy, light, heavier than, lighter than
Mastery Evidence
- Heft two objects and say which is heavier/lighter
- Use a simple balance to compare the weight of two objects
- Describe one object as 'heavier than' another
Assessment Prompt
“If [child] holds a bag of apples in one hand and a feather in the other, can they tell you which is heavier and use words like "much heavier than" to describe the difference?”
Curriculum Standards3 alignments
K.MD.1Common Core State Standards for MathematicsDescribe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
K.MD.2Common Core State Standards for MathematicsDirectly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
