# Math lesson plan examples

Develop an instructional mathematical unit.

Include your Lesson Plan Using Manipulatives assignment as one of the lessons.

Include four other fully developed lesson plans.

Include a summative assessment.

I need help with developing a new lesson unit plan. It can be for 2nd or 3rd grade. Thanks!

This solution is pasted below and is also **attached**, because this test box makes a hash of tables, and there are a lot of them used in these lesson plans.

For this unit lesson on Math for 2nd graders, I would choose to conduct a lesson on measurement.

The Standards for the state of Georgia for 2nd grade regarding measurement include the following, from Web page: https://www.georgiastandards.org/standards/Georgia%20Performance%20Standards/K-8%20Math%20Standards/2_Mathematics_Standards_REVISED_September_11_2008%5Ba%5D.pdf

Students will understand length, time and temperature and choose an appropriate tool to measure them.

M2M1. Students will know the standard units of inch, foot, yard and metric units of centimeter and meter and measure length to the nearest inch or centimeter.

a. Compare the relationship of one unit to another by measuring objects twice using different units each time.

b. Estimate lengths, and then measure to determine is estimations were reasonable.

M2M2. Students will tell time to the nearest five minutes and know relationships of time such as the number of seconds in a minute, minutes in an hour and hours in a day.

M2M3. Students will explore temperature.

a. Determine a reasonable temperature for a given situation.

b. Read a thermometer.

These standards will form the basis of the five lessons: the first, linear measurement in English Standard, and second in Metric, and third, estimation and comparison of the two. Fourth, telling time, and fifth, temperature (with some volume measurement thrown in for pre-viewing 3rd grade standards). So, the first three lessons will cover standard M2M1, the fourth will cover M2M2 and the last will cover M2M3 (all the lessons will use objects for measuring and hands-on activities, so manipulatives are included in all of them, to one degree or another).

Measuring Unit 2nd Grade, Lesson 1

English Standard Measurement

Standard: M2M1. Students will know the standard units of inch, foot, yard and metric units of centimeter and meter and measure length to the nearest inch or centimeter.

a. Compare the relationship of one unit to another by measuring objects twice using different units each time.

b. Estimate lengths, and then measure to determine is estimations were reasonable.

Materials: English/Metric rulers, Yardsticks, tape measures. Objects to measure, handouts

Procedure: Introduce the concept of measuring by ordering the students in the class from tallest to shortest. Teacher MEASURE each student, record heights on chart below. Chart the student's heights, and let them help you place the data on the chart. Use the following recording sheet:

Student's Name Height Rank from shortest to tallest

Show students measuring increments on the board: inch, foot, yard. Explain that there are 12 inches in a foot, and three feet in a yard. Ask comprehension questions orally, check.

Explain that the rulers have two scales on them, English Standard and Metric, Explain that we will use Metric tomorrow - today we will use English Standard. Show students the numbers on the instruments, ruler to measuring tape, and explain that the smaller divisions are for next year's lessons, and that for right now, they need only to know the whole numbers. Demonstrate, to the whole class, measuring using each instrument. Cover enough examples to get answers from each child in the group to check for understanding.

Divide students into small groups of three students, and distribute measuring tools, one student gets the ruler, one student the yardstick, and one the measuring tape. Give each group a measure sheet, with various objects to measure on it. Show students that small objects can be measured with the ruler, larger objects require the yardstick, and really big objects require the measuring tape. Mark items with RED tape on the side you want students to measure. Give each group the worksheet below to record their measurements.

#### Solution Summary

Series of 2nd/3rd grade math lesson plans on a measurement unit, with assessment rubrics, and Georgia state standards. At least one plan uses manipulatives.
