This tribute to math has a double meaning. It’s even arranged to look like a slice of pi. Oops, I mean pie.
- We will discuss about measuring mass. We know the vegetable seller is weighing potatoes in kilogram. The goldsmith is weighing a ring in grams. The wheat bags are weighing in quintals.
- In 2nd grade measurement of length worksheet we will solve the problems on non-standard unit of length, standard unit of length, using a scale, using a ruler and word problems on measurement of length.
- We will learn measure a length using a ruler. The ruler given below has 15 cm marked on it. The length of the ruler is 15 cm. To measure a length of a pencil, place at the ‘0’ of the ruler at the one end of the pencil and note the position of the other end.
- We will learn how to measure the length using a scale. A cloth merchant uses a rod to measure the length of the cloth. This is called a meter rod. A tailor uses a tape to take measurements for stitching a cloth. A carpenter or mason uses a metal tape to measure the 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 non-standard units of length.
- What is the standard unit of length? We know some non-standard units of length like hand-span, cubit, etc., and also with standard units of length like meter and centimetre. We have seen a meter-rod
- We will learn corners and sides of plane figures The lines that form a plane figure are called sides or edges. Two lines where they meet is called the corner.
- A plane shape is a figure made up of straight or curved lines. Two straight lines where they meet is called the corner. The straight lines which form a plane shape are called its sides. Some basic shapes are given below.
- We will discuss here about points and line segment. We know when two lines meet we get a point. When two points on a plane surface are joined, a straight line segment is obtained.
- We will learn how to draw straight lines. Fold a piece of paper and mark two dots as shown in the picture. Draw a line from one dot to another along the fold. The line we get is a straight line. The dots are known as points. We use capital letters like A, B, C, D to name the
