1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

This lesson is designed to teach the Common Core State Standard: Measurement & Data CCSS.Math.Content.4.MD.A.1CCSS.Math.Content.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 (1, 12), (2, 24), (3, 36),... CCSS.Math.Content.4.MD.A.2CCSS.Math.Content.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.

3. Who is brave enough to catch a wave in Kachemak Bay in Alaska? Don “Iceman” McNamara, for one. McNamara lives on the shore of the bay in Homer, a fishing town on the Kenai Peninsula that dubs itself "the cosmic hamlet by the sea." McNamara is part of a growing group of surfers who find the bracing waters of Kachemak Bay just another welcome challenge. One imagines they subscribe to the old surfer adage, "Surfing is life; the rest is details."
