## Flips, Slides, and Turns

### Renee Duncan

#### Description

This activity is a hands-on way for students to practice manipulating and drawing shapes to demonstrate the concept of flips, slides and turns. This lesson is especially beneficial to tactile and visual learners.

#### Objectives

The student identifies and performs flips, slides, and turns given angle (90o, 180o) and direction (clockwise or counterclockwise) of turn, using concrete and graphic materials (for example, pattern blocks, geoboards, grid paper).

#### Materials

-Construction paper
-Pre-cut letters E and L from Ellison machine ( each student gets an “E” and an “L”)
-Pre- cut 1 small and 1 large construction paper triangle for each student
-1 large arrow shape cut from construction paper
-envelopes
-grid paper-(graphing paper) (2-3 pieces to allow for corrections)
-teacher-made multiple choice activity sheets requiring students to identify flips, slides, and turns
or workbook sheets from math book correlating with this lesson.

#### Preparations

2. Draw a set of 10 angles on the board before class begins, making sure that several 90 degree angles are shown as well as several 180 degree angles.
3. Cut out a set of the following figures and place in an envelope for each student: 1 letter “E” and 1 letter “L” from the Ellison die cut machine, a large arrow design, 1 large triangle and 1 small triangle. Make a teacher demonstration set also.
4. Gather 3 sheets of grid paper (graph paper) per student.
5. Make copies of teacher made multiple choice questions or workbook pages from math book correlating with this activity.
6. Provide a pencil with a good eraser for each student.

#### Procedures

1. Review orally concepts of 90 degrees and 180 degrees by having students identify the angles from drawings on the board. Call on a student to circle all of the 90 degree angles and another student to underline all 180 degree angles. Discuss accuracy as a group and make corrections if necessary.2. Explain to the students that they will be learning about how to flip, slide and turn figures without changing their shape or size.
3. Distribute envelope to each student containing letters E, L, triangles, and large arrow shapes. The teacher has an envelope with these shapes for demonstration purposes.
4. Open envelope and hold up each figure one at a time, asking students to practice moving the shapes around in various positions on their desks.
5. Hold up letter “E”. Place the letter on overhead, and demonstrate a 90 degree turn.
6. Ask students to turn their “E” 90 degrees.
7. Monitor students for accuracy.
8. Do the same for letter ”E”, turning 180 degrees.
9. Repeat the procedure for letter “L”, the arrow, and triangles.
10. Demonstrate using the overhead sliding each of the items in the envelope to another side of the paper.

11. Ask students to do the same, monitoring their progress.
12. Demonstrate flipping each of the items in the envelope on the overhead.
13. Ask the students to do the same, monitoring progress as they work.
14. Demonstrate on the overhead how to draw the figures on grid paper as they are in the flipped, slid and turned positions.

15. Provide an oral exercise with class to determine examples and non examples of flips, slides and turns.
16. Have students trace each figure from their envelope on grid paper (graph paper) in upright , correct position. Next to each figure have the students draw the figure in the flipped, slid and turned 90 degree positions and 180 degree positions, labeling each figure underneath. Explain to them that the rubric will be used for grading and show them a copy as you explain it. Tell them that spelling does count since keys word have been provided for them to use on the overhead.)
17. Students will check their work to make sure directions have been followed. ( an answer key may be provided to allow self-checking, or they may want to check with a peer.)
18. Students will complete multiple choice worksheets provided to identify figures in flipped, slid, and turned positions.

#### Assessments

Use completed grids to formatively assess the student’s ability to:
-use figures to determine(label) and draw flips , slides, and turns (90 degrees and 180 degrees).
See rubric for criteria for successful performance. (See Associated Files.)
-students will correctly identify flips, slides and turns in a multiple choice format.
- students will confer with teacher after grading has been done according to the rubric before completing a multiple choice worksheet
with sample problems.

#### Extensions

Modifications for students may be necessary if the student has visual perceptual difficulties. If a student is having difficulty in this area, close monitoring will be necessary to make sure that the figures are being drawn in the correct space. Some students may need assistance in tracing the figure on the grid.

Students may practice this skill independently by using the Math Arena game on the Sunburst Communications math CD.

After assessing each student's paper with the rubric, have a conference with the student to make sure they understand how to correct their mistakes.

This lesson could be used as a review for the equivalent fifth grade standard.
