Recognise and use thousandths; relate them to tenths, hundredths, and their decimal equivalents (e.g. 1/1000 = 0.001, 35/1000 = 0.035)
The rain gauge needs finer marks to measure last night's rain. You already know tenths (0.1) and hundredths (0.01). Cut a hundredth into 10 even smaller pieces, and each piece is a thousandth. A thousandth is written 0.001, or as the fraction 1/1000. One hundredth is 10 thousandths, and one tenth is 100 thousandths.
Priya measures 0.035 liters of medicine. She checks the digits after the point: 0 tenths, 3 hundredths, 5 thousandths, which is 35 thousandths in all. As a fraction, that is 35/1000.
Count the digits after the decimal point. Three digits means thousandths, so 0.006 is 6 thousandths, not 6 hundredths.
Three decimal places means thousandths, and one hundredth is worth 10 thousandths.
Last market day you chalked 3/10 as 0.3 on the stall board. The rain gauge by the shed is a tall jug that holds one liter when it is full. Its tall marks cut the liter into 10, so each tall mark is a tenth.
Leo counts 10 smaller marks between two tall marks. What is one small mark worth?
