4.MD.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 twocolumn 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), ...

Dunk Tank is a maththemed game show created by the producers of Cyberchase and starring Harry from Cyberchase For Real. Using a combination of video and interactive gaming, each program addresses a single topic in the 6th grade math curriculum and s...tudents compete with themselves for high scores. Dunk Tank is an independent learning experience for students to complete in 1530 minutes, depending on their proficiency, and can also be used to support teacherled instruction. In this interactive, Harry explains key concepts about liquid volume, including standard units of measure (what they are, when to use them, how to convert between them). Students play Fill It Up, a minigame that challenges students use pints, quarts and gallons to exactly fill large containers whose volume is marked only in cups; watch a comic video about the importance of measuring carefully with standard units when baking; and answer other questions designed to help them further their understanding of liquid volume. Students can access support using a glossary, defining key math terms, and a menu of short segments to rewatch.

Students learn that in the metric system, all measures of length are based on meters. For example, a centimeter is 1/100 of a meter. And all measures of weight are based on grams. For example, a kilogram is 1000 grams. And all measures of volume are ...based on liters. For example, a milliliter is 1/1000 of a liter. Students are then asked to solve problems using conversion factors, such as 4,500 milligrams = ____ grams. (01:26)

Dunk Tank is an independent learning experience for students to complete in 1530 minutes, depending on their proficiency, and can also be used to support teacherled instruction. In this interactive, Harry explains key concepts about finding the area of squares, rectangles and composite shapes, including measuring with unit squares and using the formula Length x Width to calculate area. Students play Polygonathon, a minigame that challenges them to make simple polygons and find their areas; watch a comic video about using a nonstandard unit of measure – sleeping bags! – to calculate how many friends can come for a sleepover; and answer other questions designed to help them further their understanding of area. Students can access support using a glossary, defining key math terms, and a menu of short segments to rewatch.

Students learn the following customary units of measurement: inch, foot, ounce, ton, fluid ounce, pint, gallon, yard, pound, cup, quart, and so on. Students also learn to convert from one customary unit of measurement to another using the following c...onversion factors: 60 seconds = 1 minute, 7 days = 1 week, 3 feet = 1 yard, 16 ounces = 1 pound, 4 quarts = 1 gallon, and so on. Students are then asked to solve problems using conversion factors, such as 18 feet = ____ inches. Video is good quality and good for all students as a review or initial learning of the topic.
