HOW TO DRAW A LINE SEGMENT :

HOW TO DRAW A LINE SEGMENT TO DRAW A LINE SEGMENT OF 4 ½ CM STEP 1: mark a point on a blank sheet of paper STEP 2: keep the scale with the zero mark at the point. Hold the scale firmly with left hand. STEP 3: use the other hand to draw a line from the point along the edge of scale to the mark halfway between 4 cm and 5cm.

This line measures 4.5 cm:

This line measures 4.5 cm 0 1 2 3 4 5 6

TO DRAW A LINE SEGMENT OF 4.7 cm:

TO DRAW A LINE SEGMENT OF 4.7 cm STEP 1: SAME AS BEFORE STEP 2: SAME AS BEFORE 0 1 2 3 4 5 6 7 STEP 3: draw a line from 1 to 5,it will make 4 cm and then count small lines upto 7. this will make 4.7 cm

CONVERSIONS:

CONVERSIONS WE KNOW, 1000 g = 1 kg 1 kg = 500 g + 500 g 500 g= 250 g + 250 g it means, 1 kg = (250 g + 250 g)+(250 g +250 g ) = 4 x 250 g 1 kg = 10 x 100 g

EXPRESSING cm to m:

EXPRESSING cm to m WE KNOW 100 cm = 1 m THIS MEANS 500 cm = 5 m 700 cm = 7 m 475 cm = 400 cm + 75 cm = 4m 75 cm 789 cm = 700 cm + 89 cm = 7 m 89 cm

EXPRESSING m to cm:

EXPRESSING m to cm 1 m = 100 cm THIS MEANS, 5 m = 500 cm 2 m = 200 cm 8 m = 800 cm 1m 80 cm = 100 cm + 80 cm = 180 cm

MORE EXAMPLES:

MORE EXAMPLES 6 m 45 cm = 600 cm + 45 cm = 645 cm 3 m 6 cm = 300 cm + 6 cm = 306 cm 9 m 9 cm = 900 cm + 9 cm = 909 cm

EXPRESSING m to km:

EXPRESSING m to km We know , 1000 m = 1 km So, 2000 m = 2 km 7000 m = 7 km 4000 m = 4 km

MORE EXAMPLES:

MORE EXAMPLES 7358 m = 7000 m + 358 m = 7 km 358 m 4309 m = 4000 m + 309 m = 4 km 309 m 2500 m = 2000 m + 500 m = 2 km 500m

EXPRESSING km to m:

EXPRESSING km to m If 1000 m = 1 km , then 500 m = ½ km So, 5 ½ km = 5 km + ½ km = 5000 m + 500 m =5500 m

MENTAL MATHS:

MENTAL MATHS Express in m : A) 200 cm B) 909 cm C) 751 cm D) 430 cm

Express in cm:

Express in cm A) 9 m B) 8m 47 cm C) 6 m 9 cm D) 8 m 1 cm

Express in km:

Express in km A) 6000 m B) 7100 m C) 4325 m D) 8920 m

Express in m:

Express in m A) 6 km B) 9 ½ km C) 5 ½ km D) 2 km

Application in real life:

Application in real life Que: Rakesh walked 470 m from his house to the market and back again . What distance did he walk in all? house M A R K E T 470 m 470 m

Answer to question:

Answer to question This means in total Rakesh walked ( 470 + 470 ) m = 940 m Rakesh walked 940 m in all.

Question:

Question Pooh jogged 5 times around a park that had a path of length 400 m. how many km did he jog? PATH 400 m

Answer to question:

Answer to question In one round he covered 400 m and he took 5 such rounds. So, distance covered by him in 5 rounds will be 400 m x 5 = 2000 m = 2 km

Question:

Question Rani has 9 stamps that are each 3 cm long. Will all 9 stamps fit into a single row across a stamp album that is 24 cm across ? Across ( 24 cm)

Slide 30:

3cm 3 cm 3 cm 3 cm 3cm 3 cm 3 cm 3 cm If we place 8 stamps side by side , then it covers 24 cm. this means if we place 1 more stamp , then it will go out of the book. ANSWER: NO, ALL 9 STAMPS WOULD NOT FIT ACROSS

THE END:
