Multiply by 1 | Learn Multiplication | Multiply By Music | Jack Hartmann Teacherflix 5 Vues • 2 années depuis

Multiply by 1 and learn the multiplication facts for the 1 times table. This song has cool original music that is very contemporary and age appropriate for 2nd through 5th graders. Also, this song goes through each table 1 through 12 three times to give your children a chance for lots of practice. We take pride in saying that this is one of the best multiplication facts songs on the market.
This song also has a gradual learning structure.

First time: I sing the multiplication table I give the answer.

Second time: I say the table I delay the answer, so children have a chance to answer before me.

Third time: I completely omit the answer so children can answer on their own.

This song on learning how to Multiply by 1 is a wonderful way for your children to learn and practice the multiplication tables.

LYRICS:

Any number multiplied by one
You get that number and you’re done
Any number multiplied by one
You get that number and you’re done

1 x 1 is 1
1 x 2 is 2
1 x 3 is 3
1 x 4 is 4
1 x 5 is 5
1 x 6 is 6
1 x 7 is 7
1 x 8 is 8
1 x 9 is 9
1 x 10 is 10
1 x 11 is 11
1 x 12 is 12

Any number multiplied by one
You get that number and you’re done
Any number multiplied by one
You get that number and you’re done

Now you say the number before me

1 x 1 is 1
1 x 2 is 2
1 x 3 is 3
1 x 4 is 4

The Simplest Math Problem No One Can Solve - Collatz Conjecture Teacherflix 5 Vues • 2 années depuis

The Collatz Conjecture is the simplest math problem no one can solve — it is easy enough for almost anyone to understand but notoriously difficult to solve. This video is sponsored by Brilliant. The first 200 people to sign up via https://brilliant.org/veritasium get 20% off a yearly subscription.

Special thanks to Prof. Alex Kontorovich for introducing us to this topic, filming the interview, and consulting on the script and earlier drafts of this video.
