[L2] A Journey Across Lakes
Practice
Lesson 2 to practice converting and comparing measurement units of length by analyzing lake lengths. CC Standard: 4.MD.A.1: Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs. 4.MD.A.2: Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

A Journey Across Lakes Scientists studying lakes around the world often have to compare and convert their lengths. Since lakes are uneven, scientists use the longest straight line across to measure length—like a ruler across a lake’s widest point.
