This category examines the Common Core standards 2.MD.1 - 2.MD.10 (or 2.MD.A.1 - 2.MD.D.10). You can find helpful guides that provide videos and activities to help you teach these math standards here! Feel free to click through and find what you need!
The first four standards (2.MD.1, 2.MD.2, 2.MD.3, & 2.MD.4) discuss how to measure and estimate lengths in standard units. The first standard covers how to choose measuring tools that are appropriate for the job. For instance, a bunny probably wouldn’t be the best measuring tool, but you can use a ruler to measure a bunny. Next, students learn how to measure an object twice with different tools, explaining how the measurements relate.
Standards 3 and 4 cover measuring objects with specific units like inches, feet, meters, etc. After, students determine how much longer one object is from another, using the correct terms.
The next two standards (2.MD.5 & 2.MD.6) relate comparing addition and subtraction to length. Standard 5 has students add and subtract within 100 to solve word problems that involve lengths with the same units. The 6th standard then has your students represent numbers as lengths on a numberline. By starting at 0 and ending at the given number, students can visualize how “long” a number is.
Standards 2.MD.7 and 2.MD.8 lets students work with time and money. First, students learn how to read both digital and analogue clocks, rounding to the nearest 5. Additionally, your students will be able to solve word problems involving different types of money (i.e. dollars, pennies, nickels, etc.). Word problems will use terms like cents (¢) and dollars ($) and involve addition and subtraction.
The last two standards (2.MD.9 & 2.MD.10) discuss representing and interpreting data. By measuring the lengths of various objects, students can gather data and represent these data findings via a line plot. At this point, students work with whole numbers only. Finally, students can draw a picture graph or bar graph and represent the data set, with up to 4 categories. Afterwards, students can use the information to analyze and compare problems.
