### Lesson Plan Title : Estimating with Ties

Age Range: Kindergarten through grade 2 (Primary)

Overview and Purpose: When you think of Father's Days, you think of ties. In this activity, students use ties to practice estimating.

Objective: The student will be able to estimate how many pictures are on a tie.

Resources:

Several ties with pictures on them (dots, ducks, golf clubs)

Teacher created worksheet

Tag board or construction paper

Tie pattern

Markers/crayons/colored pencils

Stickers

Activities:

Hold up a tie and have students guess how many objects are on it. Write their guesses on the white board or a piece of chart paper. Count with them how many are on it and record that answer also. Divide the students into groups of three and have them complete the worksheet using three different ties.

After they have completed the worksheet, have each child make their own tie using the pattern. They can decorate it by drawing objects on it or using stickers. Have them write the total number of objects on the back of the tie. Check the answers to make sure they are correct and laminate the ties. Place them in a center and have the students use them to practice estimating.

Review the worksheet.

Wrap Up:

This activity could be extended by having them complete another worksheet at home with their dad, using either his ties or two they make together.
