Measurement of Length
We can measure objects by comparing them with other objects like
clips, ribbons, pencils or using our body parts for example handspan, foot,
cubit and stride. These are nonstandard units of length.
We see many things around us. Some are short in length like pencil, crayon or a toothbrush. Some objects are long like ladder, tree or buildings.
We have learnt to measure objects by using body parts like fingers,
handspan, cubit and footspan. We can also compare length of two objects
by using the body parts.
We can also use different objects like clips, pencils, ribbons to measure the length.
The length of the pencil is about 8 paper clips.
The length of the pencil box is about 9 clips.

Practice the math worksheet on third grade geometrical shapes. The questions will help the students to get prepared for the third grade geometry test. 1. Name the types of surfaces that you know. 2. What types of surfaces do the following objects have?

We can estimate some lengths and distances using approximate value for measurements. For example, one meter is approximately the length from shoulder to fingertips of an adult. A meter is also approximately the distance of one large step or jump. You must have seen the cloth

In 3rd Grade Geometrical Shape Worksheet we will answer the different type of questions on straight line, curve line, plane shape, solid shapes, drawing solids on a lat surface, and tangrams.

A map is a drawing that gives us information about the place. For example, a map of a bedroom might show where the bed,, dressing table, cupboards are. A map of a city or a locality shows streets, highways, schools or landmark etc.

Tangram is a traditional Chinese geometrical puzzle with 7 pieces (1 parallelogram, 1 square and 5 triangles) that can be arranged to match any particular design. In the given figure, it consists of one parallelogram (6) one square (4) and five triangles (1. 2, 3,5 and 7)

We can draw 3D shape like cube, cuboid, on a dotted sheet. There are two different sheets – ordinary sheet and isometric sheet. Isometric sheet is a special paper with dots at equal distance, which help us to draw 3D shapes.

In third grade geometry activities kids will learn about the basic shapes (solids). We know, about some of the geometrical shapes like cuboid, cube, cylinder, cone, sphere, triangular prism, etc.

What are the different types of lines? There are two different kinds of lines. (i) Straight line and (ii) Curved line. There are three different types of straight lines. (i) Horizontal lines, (ii) Vertical lines and (iii) Oblique or slanting lines.

Definition of in Linesegment, ray and line geometry: A line segment is a fixed part of a line. It has two end points. It is named by the end points. In the figure given below end points are A and B. So, the line segment is called AB. A line segment is denoted as AB

Practice the third grade math worksheet on point, lines, linesegment and ray in geometry. The questions will help the kids to understand the basic concept of point in geometry; lines
