# Classroom Videos

Clips of teaching videos are taken from actual teaching classroom. These videos are very short in duration but every video revolves around different themes of teaching which can be explore.

- Where fractions are used in daily life? – Here teacher explains that with the help of fractions we can tell ‘exactly how much?
- Fractions through equal sharing – Here teacher explains how fractions can be thought of as shares in equal sharing situation.
- Equal Sharing as ‘division’ – The point of discussion here is how division and equal sharing are related to each other?
- Introduction of unit fractions – Unit fractions are made familiar to students by equal sharing situations.
- Comparison of unit fractions – When more people share one whole (Cake, Chappati, etc.) the size of share decreases is explained to the students as comparing unit fractions.
- Importance of size of whole while comparing fractions – How size of whole plays important role in comparing fractions is explained here.
- Introduction of Composite fractions – Composite fractions as built up from unit fractions and also explained through sharing situation.
- Drawing 2/5 of 40 – Here teacher has asked students to draw 2/5 of 40 on the board. Also asked students to estimate 40 liters.
- Writing fraction for a tricky whole – Students are responding to a non-traditional whole.
- Completing a whole – How to complete a whole using different unit fractions is discussed here. (One unit fraction at a time.).
- Comparing 1/3, 3/3 and 3/1 – Through unit fraction and sharing situation explanation.
- Equivalent fractions through sharing situations – By grouping method.
- Is 4/5 equal to 5/6? – Discussing whether adding same number to the numerator and denominator of a fraction give equivalent fraction.
- Multiplying by Unit fractions – The concept of multiplying by unit fractions as dividing by the denominator is generalized here.
- Introduction of multiplier diagram.
- Difference between Multiplicative comparison and Additive comparison – ratios are introduced using these comparisons.
- Introduction to types of ratios – Here within and across ratios are introduced using examples.
- Ratio proportion word problems using number line method – A word problem is solved here using number line method.
- Interpreting 50/60 as a part of a cake – SN – 01-06-07
*(Marathi)*Here SN asks students to draw 50/60 of a cake on the black board. - Comparing Fractions – How size of wholes is important? Here KS explains why we assume size of wholes same while comparing fractions using sharing situation.
- Comparing Fractions using unit fractions – How size of wholes is important? – Here KS explains why it is necessary to keep wholes same while comparing fractions using unit fractions comparison.
- Comparing Fractions by decomposing composite fractions – Same numerator and same denominator Here KS explains how to compare same denominator fractions as well as same numerator fractions by decomposing the composite fractions into unit fractions.
- Need for composite fractions – Here KS explains why there is need for composite fractions. Why can’t we rely only on unit fractions?
- How children respond to non-traditional wholes – Here KS explains how the choice of whole strengthens fractions understanding.
- How three fourth is same as 0.75? – Here KS discusses with children how decimal numbers are same as fractions.
- Discussion on three fractions: 1/3, 3/3, and 3/1 – Here KS discusses these three fractions.
