There are many things you could use to teach significant figures successfully such as food. M n Ms. are an excellent food to use to teach significant figures.
Use a calculator. Schools no longer teach the by-hand method of determining square roots (that's differential calculus, don't worry about it).
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
If the figures in the table are exact and without measurement error then take any two of the points (x1, y1) and (x2, y2) and use these to form the linear relation y - y1 = ((y2 - y1)/(x2 - x1))(x - x1) If, however, you suspect that the values in the table do not exactly follow a linear relationship then use linear regression for which formulae are provided in wikipedia.
Here is a website with a method for determining the square root of any number: http://www.jimloy.com/arith/sqrt.htm Using a calculator, the closest square root of 4086248736408 to 8 significant digits is 2021447.2. You need to use the method referenced in the URL to find the answer to additional significant digits. If the answer can be divided by any whole number and the result is a whole number, then the square root is a rational number.
A simile that fits the prompt "as tall as a" could be "as tall as a giraffe." This comparison highlights the significant height of the subject by relating it to the well-known tall animal. Similes use "like" or "as" to create vivid imagery, making it easier for the reader to understand the height being described.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
when rounding you want to choose an answer with the lowest significant figures to have a better answer choice
Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
You just did. Here's two more: The number 303 has three significant figures. George Washington and Thomas Jefferson were significant figures in the American Revolution.
The number of significant figures after the decimal place matches the number of significant figures before the computation of the logarithm. Thus ln(3.02) would compute to 1.105. Three significant figures to four significant figures (3, after the decimal place).
In multiplication and division, the number of significant figures in the result is determined by the measurement with the fewest significant figures. For example, if you multiply 4.56 (three significant figures) by 1.4 (two significant figures), the result should be reported with two significant figures, yielding 6.4. Always round the final answer to reflect this limitation.

the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.
4 significant figures in 4400. A digit within a number is considered significant if: 1. it is a non-zero OR 2. It is a zero that is between two significant figures OR 3. It is a zero at the end of the number To express four thousand four hundred with two significant figures use scientific notation: 4.4 * 103
The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 270.9
