Decimal

A manipulative is often used in many ways to teach mathematics such as basic addition, fractions, decimals, order of operations. To name a few manipulatives; blocks, cards, number tiles, counting tubes, etc…A manipulative can be taught either concrete (hands-on) or virtual. Hands-on manipulative models are physical objects such as base-ten blocks, deck of cards, Dice games, and Algebra tiles. A virtual manipulative is a technology that models the existing manipulatives such as base ten blocks,

not to the same level of accuracy. A computer would input a value for ? on both sides and if the answer is equal then the equation is equal. The problem with this is that when you get into trigonometry there could be a difference in the decilionth decimal place. A computer can’t work with the abstract which is what is in my example. A computer may take 2 seconds or a million years to find an answer or it may give the wrong answer! The other point is that a computer can only perform things in a certain

have health insurance? Place your answer, rounded to 2 decimal places, in the blank. 14.15 Do not use a percent sign. For example, 17.76 would be a legitimate entry. Answer Key: 13.00|15.00 | Question 2 of 20 | 1.0 Points | | MATH302_Midterm.xls | 30 KB | The

understand simple decimal subtraction (question 1a), decimal point placement (question 2a) in a multi-digit number and simple decimal multiplication (question 6). All three of my selected students correctly answered 1a and 2a proving that students across all ability levels were able to master this specific content. As for number six, two out of these three students answered it correctly. It was apparent that the majority of my students struggled to understand the concept of multi-digit decimal division (question

digits are significant and which are not. In order to determine the significance of number, you must know that all non-zero digits are significant and that all zeros that are between non-zero digits are significant. Trailing zeros to the right of the decimal point are significant, whereas leading zeros

Then we got then unknown Cobalt (II) solution and placed it in a cuvette to measure the light transmittance recording it to three decimal places. Next, the unknown solution of Cobalt (II) was placed in a 100 mL beaker and the DI water was placed in a smaller beaker to make transferring the solutions easier. For the process of transferring each solution smoothly, a pipette will be used

Leonardo based this book on the mathematics and algebra that he had learned through his travels. The name of the book Liber abbaci means book of the abacus or book of calculating. This was the first book to introduce the Hindu-Arabic place value decimal system and the use of Arabic numerals in Europe. Liber abbaci is predominately about how to use the Arabic numeral system, but Leonardo also covered linear equations in this book. Many of the problems Leonardo used in Liber abacci were similar to
