Here are the square roots of all the perfect squares from 1 to 100. Finding square roots of of numbers that aren't perfect squares without a calculator. 1. Estimate-first, get as close as you can by finding two perfect square roots your number is between. 2. Divide-divide your number by one of those square roots. 3.Average-take the average of the result of step 2 and the root. 4. Use the result of step 3 to repeat steps 2 and 3 until you have a number that is accurate enough for you.Example: Calculate the square root of 10 () to 2 decimal places. 1.

Kumon offers math and reading at a monthly cost ranging from $80 to $100 for a single subject, with a beginning registration fee of $50, and material fees of $15. Again, the fees associated are set at the determination of each franchise owner, as are the hours of operation, and will vary.
(I also enjoy working with each of the students, so there's a double advantage if you are in our area.) The cost recently went up and is now about $110/mo. per subject (Math and/or Reading) - this may vary slightly from center to center-not sure.., I did Kumon with my 8 yo in NJ from Apr to June the following year. He hated every minute. Math just isn't his thing, nor was Kumon. I loved the program and concept. The registration fee was either $50 or $100 and then it was $100 every month.
