 1 centimeter (cm) = 10 milimeters (mm) 1 decimeter (dm) = 10 cm 1 meter (m) = 10 dm 1 m = 100 cm = 1000 mm. 1 kilometer (km) = 1000 m 1 cm = 1/100 m 1 mm = 1/10 cm 1 m = 1/1000 km

 Complete the following: Solutions 1) 1 m 2 dm = 120 cm 1 m = 100 cm; 2 dm = 2 x 10 cm = 20 cm; 100 cm + 20 cm = 120 cm 2) 2 km 45 m = 2045 m 2 km= 2 x 1000 m = 2000 m; 2000 m + 45 m = 2045 m 3) 2 cm 6 mm = 26 mm 2 cm= 2 x 10 mm = 20 mm; 20 mm + 6 mm = 26 mm; 4) 400 cm = 4 m 400 cm = 400 x (1/100) m = 4 m 5) 40 cm =  4 dm 40 cm = 40 x (1/10) dm = 4 dm 6) 2 m 1 dm = 210 cm 2 m = 2 x 100 cm = 200 cm;  1 dm = 10 cm; 200 cm + 10 cm= 210 cm; 7) 4 m 6 cm = 4060 mm 4 m = 4 x 1000 mm = 4000 mm; 6 cm = 6 x 10 mm = 60 mm; 4000 mm + 60 mm = 4060 mm 8) 60 mm = 6 cm 60 mm = 60 x (1/10) cm = 6 cm 9) 1 km 330 m = 1330 m 1 km = 1000 m; 1000 + 330 m =1330 m. 10) 3000 m = 3 km 3000 m = 3000 x (1/1000) km = 3 km 11) 3 km 50 m = 3050 yd 3 km = 3 x 1000 m = 3000 m; 3000 m + 50 m = 3050 m 12) 180 mm = 18 cm 180 mm = 180 x (1/10) cm = 18 cm

 Write < (less than) , > (larger than) or = (equal) in the empty squares 1) 6 m > 460 cm 6 m= 6 x 100 cm = 600 cm 2) 2 m < 23 dm 2 m = 2 x 10 dm = 20 dm 3) 45 cm > 2 dm 3 cm 2 dm = 2 x 10 cm = 20 cm; 20 cm + 3 cm = 23 cm 4) 96 mm > 4 cm 4 cm = 4 x 10 cm = 40 mm
