Measurement - length, mass, capacity and volume

Students compare the lengths of two objects by placing them side by side and determining which is longer or shorter.

1.MD.A.1: Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Students use a third object to compare the lengths of two objects that cannot be placed next to each other.

1.MD.A.1: Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Students order three objects from shortest to longest and longest to shortest, using direct and indirect comparison.

1.MD.A.1: Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Students describe lengths using comparative language and solve problems involving ordering objects in real-world situations.

1.MD.A.1: Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Students measure objects by laying same-size units end to end with no gaps or overlaps.

1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the le...

Students measure two objects using the same non-standard unit and compare their lengths by number of units.

1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the le...

Students discover that using different-sized units gives different measurements, motivating the need for standard units.

1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the le...

Students practice measuring a variety of classroom objects using non-standard units, recording and discussing their measurements.

1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the le...

Students explore the parts of an analog clock, identifying the hour hand and the minute hand and their roles.

Students read and write times to the hour on both analog and digital clocks, using o'clock language.

Students read and write times to the half hour, noticing that the minute hand points to 6 and the hour hand is between two numbers.

Students practice telling and writing time to the hour and half hour in mixed exercises and real-world contexts.
