Here is our first exploration into the Flipped classroom!
Watch the video below and answer the quiz that follow online.
For parents and students, below is also an explanation of the lesson within the curriculum!
This lesson is provided by the Khan Academy and it is a series of video lessons about measurement, which ends with an online quiz and review questions.
I am specifically using the first half of the lesson, which uses the metric system and not use the second part of the lesson, which includes the US units of measurement.
The first video is about converting time, with minutes changing to hours. The video uses division and fractions to show how to convert time, allowing the students to use knowledge and skills they should already posses. This video and method can get slightly confusing, so students should already have a good knowledge of telling time, using fractions and decimals. The video could even be used for students who need a different way of converting time.
The second video looks at converting distance. The video goes over the prefixes of distance and how we can write distance as fractions. The goal in the video is to order the distances from smallest to greatest and to do that they convert all the listed distances to meters. The video also discusses how we need to look at the language in math first, even before the numbers. This lesson could be integrated with a literacy lesson to discuss prefixes and changing the meaning of words.
The third video is a focus on converting centimeters to meters. Again they use the skills of fractions, decimals and division to explain how to do the conversion.
The lesson ends with written reviews and a quiz using the conversion methods they have demonstrated.
The lesson could be used in a flipped classroom, as that is how Kahn structures their resources. It could also be used as an introduction activity for the class. The teacher can them build off what the video taught the students or teach them other ways to convert distance.
Curriculum connections: Grade 4 Measurement:
• estimate, measure, and record length, perimeter, area, mass, capacity, volume, and elapsed time, using a variety of strategies;
• determine the relationships among units and measurable attributes, including the area and perimeter of rectangles.
· – estimate, measure (i.e., using an analogue clock), and represent time intervals to the nearest minute;
· – describe, through investigation, the relationship between various units of length (i.e., millimetre, centimetre, decimetre, metre, kilometre);
· – select and justify the most appropriate standard unit (i.e., millimetre, centimetre, decimetre, metre, kilometre) to measure the side lengths and perimeters of various polygons;
· – compare and order a collection of objects, using standard units of mass (i.e., gram, kilogram) and/or capacity (i.e., millilitre, litre);
Achievement chart connections:
The lessons themselves focus more on Knowledge and Understanding, as listed within the achievement chart. Students are expected to learn a new concept and then demonstrate their knowledge and ability to implement the new method they learned.
The lessons also included thinking, as the students are expected to organize the problems and follow a set plan to convert the measurements.
The lesson also allows for application in a simple sense. The students apply what they learned from then video to help them answer the quiz questions.
