Give a seven-year-old a ruler and ask how heavy their backpack is, and they may try to measure it anyway. This 2nd grade choose a measuring tool worksheet starts from that mix-up. Each of the four questions names something to measure, then shows four tools in pictures with a box to tick. The pictures include a ruler, a stopwatch, a beaker and a weight scale. You will also find a thermometer, a measuring tape, a calendar, a clock and an alarm-clock timer. Your child decides what to measure first, weight, length or time, then picks the tool that fits. A second page gives the answer key.
