How to Use This Pack

Six pages about changing one unit into another. Page 1 is a conversion chart with pictures: a ruler, a yardstick, and a meter stick for length; measuring cups, pint and quart cartons, a gallon jug, and a liter bottle for capacity; pan balances for weight and mass. Every other page starts with a conversion key, so students practice with the facts in front of them. Page 2 fills in feet, yards, and meters tables and compares lengths with >, <, or =. Page 3 shades the cups and quarts that fill bigger containers, then has tables and comparisons. Page 4 does the same for pounds and ounces, kilograms and grams, with real things to weigh. Page 5 mixes every kind of unit: circle the bigger unit, true or false, and missing numbers. Page 6 has eight word problems.

In the Classroom

Hang the chart on the wall or give each student a copy for a folder. Before page 3, pour water from a measuring cup into a pint and a quart container so students see 2 cups fill a pint. Read each key fact as a multiplication: 3 yards is 3 groups of 3 feet, so 9 feet.

At Home

Look at labels in the kitchen together: a gallon of milk, a pound of butter, a liter of soda. Ask how many quarts are in the milk jug or how many ounces are in the butter, and check with the chart.

Tips for Success

• Find the fact you need in the key before you start
• Going from a big unit to a small unit, multiply: 4 feet is 4 x 12 = 48 inches
• Going from a small unit to a big unit, think how many groups: 36 inches is 3 groups of 12, so 3 feet
• To compare, change both amounts to the same unit first
• Always write the unit with the answer
