I made this presentation to introduce my students to percents. I use this as part of my lecture to promote classroom discussion and for students to take notes from. The show walks students through the idea of breaking apart the word percent into per and cent, and it leads students through a look at both of those words/affixes. The goal is to get students to understand that percent means out of 100. The next few slides focus on converting both fractions and decimals into percents. They wal

This file contains both of my fraction and decimal number line files. I use these as problem-solving activities during our fraction and decimal units. Students are given a strip of paper that is set up like a number line. They are asked to correctly place fractions and decimals on the number line. In the process, they need to use their knowledge of comparing, ordering, and converting (fractions and decimals). We first do the fraction activity and then I give them the same number line weeks

I made this activity to use as a problem-solving activity after I've taught the basic concepts within our decimals unit. In this activity, students are given 10 decimal cards and a strip of paper, and they are asked to correctly place the cards on the strip of paper to form a decimal number line. Students must use their knowledge of what is a decimal, comparing decimals, and equivalent decimals to correctly place each decimal. This file contains teacher directions, the student decimal cards, an

This sheet assesses students basic understanding of decimals. Students are asked to identify the value of digits in decimals, write decimals in standard and word form, plot decimals on a number line, order decimals, and convert decimals to fractions and fractions to decimals.

The company quoted him .002 cents per kilobyte, but they charged him as if his rate was .002 dollars per kilobyte. The phone company contends there is no difference between .002 dollars and .002 cents, while the customer is trying to get them to understand that they are. The actual phone call can easily be found on the web
