how can i use Lego bricks to teach fractions to year 7?

We Answered:

You could use the big blocks as 1's, the squares as 1/2's and the small 2-peg ones as 1/4's. If you have the 1-peg ones, you could use those as 1/8's.

Now you've got me wanting to play with Legos. Lol

how do yu teach fractions to a 4th grader ?

We Answered:

I would make a pie out of paper and cut it into 10 slices and show them that way.

Luis Said:

somebody teach me fractions?

We Answered:

I only have one quarter of the time needed to teach you half of what your asking about fractions . It would take half an hour minimum.

Oh. My 7.5 minutes are up. Have to go. Good luck

How can I teach a 2nd Grader?

We Answered:

A lot will be trial and error. Just use your imagination and things around the house.
Money is a good concept for adding and fractions. Have a dollar note, 4 quarters, 10 dimes 20 nickles 100 cents,

Fractions can be related to rewards "you and your brother are told to do the yard, you are told you will get $10 for it. You work for an hour, he works for 10. 15, 20, etc minutes. How much should each of you get".

teach me how to do something in algebra?

We Answered:

You don't normally start from a decimal value and go backwards to the square root, it's a little awkward.

For instance, the square of 19.581 is 383.41556, still not a whole number, so I can't do anything with it.

Now, assuming you are starting with the square root of a whole number and trying to factor out as much as possible, I can show you what to do.

If you start with root(384) [a number close to the original square], you can start by looking at the factors of the number. In this case, 384 is clearly divisible by 2.
384
192 * 2
96 * 2 * 2
48 * 2 * 2 * 2
24 * 2 * 2 * 2 * 2
12 * 2 * 2 * 2 * 2 * 2
6 * 2 * 2 * 2 * 2 * 2 * 2
3 * 2 * 2 * 2 * 2 * 2 * 2 * 2
Wow, that's a lot of twos!
Now, to factor out numbers from a square root requires you to take their square root as well; that's why factoring helps, because you can see pairs of factors and just cancel half of each pair.

For example, root(4) is 2, because 4 is 2 * 2. root(12) is 2*root(3), because root(12) is root(4 * 3) and root(4) is still 2. You can pull out any squares like this, and sometimes it's easier to see by factoring.

In our case we have 3 pairs of 2's, with a leftover 3 and a 2. That means that our final answer is:
root(384)
2 * 2 * 2 * root(3 * 2)
or
8 root(6)

To check this, just square whatever your pulled out and multiply by what you left in:
8 * 8 * 6
64 * 6
384
Ta-da!

I hope this helps with your original issue!

How can I better teach my daughter fractions, at this rate she will never be able to double the recipe?

We Answered:

Real life examples. Like, daddy was wrong 9 times and right once, so that makes 9/10 of his answers wrong.

Glad to see you back.
