Standards:

4.MD.1 Know relative sizes of measurement units within each system of units (standard and metric), including kilometers, meters, and centimeters; liters and milliliters; kilograms and grams; pounds and ounces; hours, minutes, and seconds. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit.

Objectives:

Math Objective: Students will be able to relate the metric system to place value and use this understanding to convert within the metric system.
Language Objective: Students will be able to use basic metric units and their prefixes to understand the value of a given unit.

Vertical Alignment:

3.MD.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot where the horizontal scale is marked off in appropriate units-whole numbers, halves, or quarters.
4.MD.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money including problems with simple fractions or decimals.
5.MD.1 Convert among different-sized standard measurement units within a given measurement system (for example, convert 5 cm to 0.05 m); use these conversions in solving multi-step, real-world problems.

Lesson Outline:

🚀Launch:

Students will use their background knowledge to add their own objects to a list of items that are roughly a centimeter in length and meter in length.
Discuss what students have learned so far about length (customary).
To make remote, record yourself explaining this part of the lesson or do a Zoom/Teams call and teach this part.

🤔Explore:

Students will solve word problems about metric units of volume and length.
Some questions you can ask:
- What is the quick way to remember metric units? King(kilo) Henry(hecto) Died(deca) (base unit) Drinking(deci) Chocolate(centi) Milk(milli)
- Which metric unit measures volume?
- Which metric unit measures length?
- How many ____ are in ____?

💬 Discuss:

✅Exit Ticket: Students will demonstrate what they have learned.

Differentiation:

Challenge: Have students who need a challenge gather 5 items, ranging in weight from heavy to light. Then have them estimate and weigh each object, using metric weights. Students will record the weights on the Metrics Place Value page. They can then convert the measurements to smaller units, such as grams.
Struggling: Encourage students who are struggling to circle the units being considered (e.g. meters and centimeters). This will allow students to focus on what is being asked without being distracted by other possible units.
