Interval Notation | Number Line | Equality and Inequality Symbols | Graphs [Animated] - Pre-Algebra

This is an ANIMATED MATH video explaining the "Interval Notation" that is VERY EASY to FOLLOW and HIGHLY RECOMMENDED for struggling students. This topic is a prerequisite for algebra.

In this video:
• 00:00 Welcome to Teach Me Animated Math!
• 00:20 Previously: Set of Real Numbers
• 00:41 Real Number Line
• 01:00 Equality and Inequality (Comparison) Symbols:
‣ 01:09 Less Than: ≺
‣ 01:27 Greater Than: ≻
‣ 01:45 Less Than or Equal To: ≤
‣ 02:18 Greater Than or Equal To: ≽
‣ 02:51 Equal To: =
‣ 03:09 Not Equal To: ≠
‣ 03:25 Approximately Equal To: ≠
• 04:02 Set-Builder Notation for numbers between endpoints
• 04:21 Interval Definition
• 04:27 Interval Notation on the Number Line: Definition + Symbols
‣ 04:41 Square Brackets: [ ]
‣ 04:49 Round Brackets/Parentheses: ( )
• 04:57 Interval Notation Examples
• 06:01 Interval Representations:
‣ Set-Builder Notation
‣ Interval Notation
‣ 06:15 Graph - brackets\parentheses
‣ 06:21 Graph - open/closed dots
• 06:36 Negative and Positive Infinity: -∞, ∞
• 07:02 Reference Table of Interval Representations
• 07:08 And there you have it!

Thank you for making this so simple and easy to follow for students!! Your channel should be recommended to schools especially those following module type of learning. Ang hirap kasi sumunod sa mga lectures kung handouts lang pagbabasihan, lalo na for visual learners. Videos like these really help a lot !!

Makakatulong rin sa side ng teachers so they dont have to make content but rather refer na lang dito.

Thanks to video creators like you, nabawasan pagka dismaya ko sa pagkawala ng mga educational shows sa tv.

[EvonneClaudineFP]

Students now a days should spend more time watching this kind of videos.
Rather than always playing online games .
This is very helpful for online classes. ^^

[blairvillanueva]

I recommended you video to my Dada's son coz like me mahina rin sa Math. Thanks for your dedication 👍👍👍

This is very relevant to the times as students are now learning at home and they look for as much material online as they can to supplement their learning.

[TheKJlifestyle]

This is an awesome instructional video for Math. It's really a great way to make Math a little less intimidating for kids. 🥰

[HappyandBusyTravels]

This is very useful specially for kids who are not yet in school, or those who still can't afford school. For adults, this is a refresher :)

[JadeOrteza]

You really have this talent to make Math easier to understand. I totally forgot this topic but your vid made it so easy for me to understand. Very helpful!

[jmarielque]

Creative way of teaching! very timely as kids are now back to school (online) mas easier to review using this kind of technique. ☺️

[elikalokaloka]

Would be perfect for those students who goes back in schooling. It will help them to easily learn about the intervals.

[TeamVallangca]

I watched this with my kids and surprisingly nakining talaga sila. They are 5 and 3 yo btw :) I know hindi pa nila talaga nilanagets pero nakakatuwa na mukhang interested sila sa numbers.

[DawnLyndelle]

Your channel is really timely po. I had a lot of trouble learning math when I was younger because I wanted more visual explanations like this :)

[allmodthings]

This is such a good way to learn and kudos for making this creative too in fact I would suggest this to my nephew . Wish this video was existing when I was struggling myself with Algebra before! 😄 Nice to know you've included time stamps as well, really helpful!

[ManilaMillennial]

Can I just say how helpful it is to see the timestamps in the description box? ♥️ You never fail to amaze. Table of contents vibe 💯

[VeeyahPenero]

This reminds me of those old TV shows like Mathtinik or something which are informative AND entertaining! The narration or explanation is clearer than some of the teachers I had in the past, so great resource! Keep up the awesome work!

[Whereispaolo]

This is an amazing refresher for everyone! Studying the basics such as real numbers and inequalities are fun lol! Cant wait for more math videos!

[wanderwomom]

thank you for this. i just sent this link to my nieces. it was really helpful daw po

[gvcaplas]

This looks easy! Bakit parang nung nag aaral pa ko sa classroom, muka syang mahirap? Hehe maybe it's the way you organize your thoughts on how to teach it here 😊

[adithya.u]

[rajintokyo]
