Description

"Translation" graphic motion PPT teaching courseware

Part One: Lesson Objectives

1. Through a series of operational activities, be able to draw simple plane graphics after translation as required, and master the characteristics of translation.

2. Combined with specific situations and operational activities, be able to use the translational movement of graphics to solve related mathematical problems.

3. In inquiry-based teaching activities, cultivate students’ spirit of active exploration and courage to discover, and understand the application value of mathematics.

Panning PPT, part 2: scene introduction

In the second grade, we already knew the translation phenomenon in life. What other translation phenomena have you seen?

Explore new knowledge

Draw the translated shape, count again, and fill in the numbers.

The shape and size of the graphics before and after translation remain unchanged, but the position changes.

Find the perimeter and area of ​​the figure below.

Perimeter: (2+4)×2=12 (cm)

Area: 2×4=8 (cm²)

Answer: The perimeter of this figure is 12cm and the area is 8cm².

Panning PPT, Part 3: Consolidation Practice

There are two intersecting paths on a rectangular lawn 30m long and 14m wide. What is the area of ​​the lawn in square meters?

29×13＝377（m2）

Answer: The lawn area is 377m2.

Problem-solving ideas:

Four pieces of lawn can be moved together to form a new rectangle. The length of this new rectangle is 30-1=29 (m) and the width is 14-1=13 (m), so the area of ​​the lawn is 29×13=377 (m2).

Find the perimeter and area of ​​this figure (the side length of each small square is 1cm).

(5+4)×2＝18(cm)

Answer: The perimeter of this figure is 18cm.

Panning PPT, Part 4: Class Summary

The position of the object after translation is determined by the direction and distance of the translation. Panning does not change the shape and size of the graphic.
