3rd Grade Rounding To Nearest Tens Lesson Plan Example

Topic: Rounding to nearest tens

Objectives & Outcomes

Students will be able to round numbers to the nearest tens place.

Materials

Worksheets with numbers ranging from 30 to 90

Rulers or meters to measure with

Warm-up

Ask students to stand up and stretch their bodies. Then, have them stand in a straight line and have them raise their hands if their number is a multiple of 10. For example, if the number is 30, students should raise their hands, but if the number is 40, they shouldn't raise their hands. Do this with a few numbers and have students call out their answers.

Direct Instruction

Introduce the concept of rounding by explaining that it is the process of finding the closest number that is less than or equal to a given number.

Show students some numbers on the board and ask them to guess what the rounded number is. Then, have them check their answers by rounding the numbers themselves.

Explain that when rounding to the nearest tens, we always round up if the last digit is 5 or greater, and we round down if the last digit is 4 or less.

Use the number cards to practice rounding to the nearest tens. Have students predict what the rounded number will be, then have them round the number themselves.

Guided Practice

Using the number cards, have students work in pairs to round the numbers to the nearest tens.

Walk around the room and check student work to ensure accuracy.

Assign a few numbers for students to round on their own, and have them use a calculator if needed.

Allow time for students to check their work and discuss any questions they have.

Independent Practice

Have students choose a number between 1 and 100 to round to the nearest tens.

Have them use manipulatives or a calculator to round the number, and record the answer on a sheet of paper.

Have students complete several rounds of this activity, and have them present their results to the class.

Closure

Review the concept of rounding with the students, and ask them to provide examples of rounding numbers.

Encourage students to continue practicing rounding with numbers in the real world.

Assessment

Observe students during independent practice and provide feedback on their ability to round numbers.

Administer a quiz to assess students' understanding of rounding to closest tens.##Evaluation

Based on their participation in the class discussions and their ability to round numbers during independent practice, assess students' understanding of rounding to nearest tens.

Use the quiz results to inform any necessary re-teaching or further instruction.
