2. General Comments
 Show and explain why we need all those things
 It is always interesting to get some historical
background for each topic
 Summarize your main topic at the end of the video

3. Collecting Like Terms
 Very creative usage of common real life analogy .
 Repeating the same thing over again with different
examples makes the message very clear.
 Nice to watch because good pace, friendly voice, and
cute little actor.
 Explain where and why we need to collect like terms

4. Metric Conversion
 Nice and clear diagrams
 Nice computer graphics
 Slower pace will make it even more clear.
 Music is very nice but distracting and making it hard
to concentrate

5. Probability
 Very good pace
 Friendly voice
 Good explanation
 Good use of diagrams
 Good variety of examples

6. Distance and Time
 I think it would be better to start with a diagram of
the trains with arrows showing their distance and
speed instead of text
 Add text comment for the formulas you are using
 00:28-end, Explain what the formulas mean more
clearly
 Express the answer in proper units
 Very good pace

7. Count To Ten
 Makes people laugh
 Repeating over again makes it silly and funny
 00:07, 00:19-00:22, 00:24, Referring to sports
practice is an interesting connection
 Represent the numbers up to ten with proper
amounts of objects

8. Equal Sign
 00:27-00:32 was an interesting historical reference
about how a person actually invented a
mathematical sign.
 00:35-00:42 Incorrect use of equal sign ( orange
doesn’t actually equal fruit, it is a subset of fruit
set)
 Confident voice
 Good pace
 I would recommend adding the history of equal
sign invention

9. What is a Square?
 Nice photos
 00:08, Showing sameness of the sides of a square
with identical twins is a very funny, cute, and
interesting connection
 Incomplete definition of a square (suits diamond as
well)
