Jessica Stacy Mathematics 1 st grade Mathematics

Today's Objective Today we will be talking about different types of shapes, learning about edges and vertices, making new shapes from old shapes and learning about faces on 3 dimensional shapes.shapes

Lets Learn About Shapes! Lets take a look at two – dimensional figures.figures Square Circle Ellipse Triangle Rectangle Rhombus Trapezoid Parallelogram Pentagon Hexagon

Edges and Vertices Shapes have edges and vertices, edges means sides.edges and vertices How many edges does a rectangle have? How many vertices does a rectangle have? Answer : 4

Making New Shapes New shapes can be made from another shape. You can combine shapes. You can cut shapes apart. What shape can be made out of a triangle? Answer : Diamond or Parallelogram

3 Dimensional Objects 3 dimensional 3 dimensional objects have faces. How many faces does a cylinder have? Answer : 3 How many faces does a cube have? Answer : 6
