Riley should have a firm understanding of comparable measurable attributes, such as height, length, amount, and size. At a glance, she should be able to create sentences describing these comparable attributes: Maria is taller than Jimmy; my glass of milk has more than your glass of milk; the school is bigger than my house. At this point, Riley should be introduced to tools used in measuring- a ruler, scale, or measurement cups. It is good practice to measure the length of things that are longer than the tool, so Riley must use problem solving to figure out how to mark where the ruler ends and then use it again to measure the next section. She should know that if the mark does reach the whole number that there are fractional amounts between each whole number. Her measuring skills can also include more abstract units, like time and money. Being able to read a clock is an exciting step in Riley’s independence. She should be encouraged to increase her awareness and responsibility for when she needs to get up, get dressed, leave for dance class, eat dinner, or go to bed. It is important that she understands minutes as fractions of an hour, so she has a strong understanding of the relationship between the two. Riley also has the knowledge to keep track of an allowance as she starts to learn the cost of things and how to count money using 5’s, 10’s, and 25’s. Riley will find lots of daily opportunities to use her measuring skills: filling the dump truck in the sand box, deciding which of her friends is the tallest, discovering which of her pet cats is heavier, knowing what time to come home from a friend’s house or helping Mom measure the ingredients to make cookies. At the end of 2nd grade, Riley should be able to solve this measurement problem: 60 cents is shared among 4 children, how much do they each get?
