Metric Concentration

Math measurement lesson plan and worksheet

Suggested grade level: 4

Measurement curriculum expectations addressed:

1. Understand metric prefixes, units and symbols

2. Know relative sizes of metric measurement units: km, m, cm, mm; Mg, kg, g, mg

3. Express measurements in a larger unit in terms of a smaller unit.

4. Measure and record length, width, height and perimeter

5. Calculate and record rectangular areas

6. Measure and record radius and diameter

Materials required:

Cardboard or paper, markers or pens, scissors, metric rulers and tape measures

Suggestions for use:

This can be done as a small group activity with groups of 2 to 5. Once the deck(s) have been created, the Concentration game may be played with pairs, small groups or as a solitaire game.

Student Worksheet 1: Measuring

Student Worksheet 2: Conversions

If shapes that tile the plane have not been discussed, tell the groups that they may do the activity with index cards if they can't think of different shapes that fit together snugly.

If radius, diameter, or area have not been discussed, replace those measurements with width and length of those or other items in the classroom or use the other "deck".

If you chose the Measuring deck, when the groups have completed their decks, have them compare the matching cards that they created and compare the measurements that they made and recorded. If there are differences, have the groups explain, demonstrate, and compare their measuring methods.

Variations and extensions:

1. Create a deck using metric sports or Olympics data (current world pole vault record, reigning Olympic 100 m dash champion, length of the race known as the "metric" mile, backstroke distance in the 400 m individual medley swimming event, etc.)

2. Have students experiment with the shapes of the cards: suggest M. C. Escher designs, alphabet shapes, more than one shape, etc.

3. Have students face new challenges and check the work of other groups by playing with a deck created by another group.
