"

**Ten cents**" 10c, 20c, 30c, 40c, 50c...100c.**One-tenth:**Count dimes touching and saying: "one-tenth" 1/10, 2/10, 3/10, 4/10,...10/10.**Decimal, 0.10:**Count dimes touching and saying: "point 1" .1, .2, .3, .4, .5, ... .9, 1.0.**HUNDREDTHS:**Next, BREAK a dime into 10 equal pieces = 10 pennies. A dime is 10 cents. Visuals. Video.**CENTS:**But each penny is a cent because**cent**means**100**and you need 100 pennies to = $1. So each penny is a**hundredth**of a dollar. 1/100 = 1c = 1 cent = 1 penny.Count 10 pennies into sets of 5.

Touch and say as you count: "1 cent, 2 cents, ...10 cents."

**One-hundredth**: Touch and say the fraction form of a penny as you count: "one-hundredth, two-hundredths, three-hundredths, 4/100, 5/100...10/100."**Decimal, 0.01**: Touch and say as you count: "point zero one, point zero two, .03, .05... .09, .10."**Percent**: Percent means for each (per) 100 (cent), for each 100. Each penny is 1 cent or 1 PER CENT of one dollar.Count percents: Touch the pennies and say as you count, "one percent, two percent, three percent, 4%, 5%, 6%....10%.

### METHODOLOGY

Don't be intimidated by math symbols. Modeling the numbers and relationships is easy with the money and the chart, but once you translate the real to the symbolic expressions on paper, we enter a fuzzy, stressful, abstract mental math area (we increase cognitive load, slow processing, and encounter more errors in speaking and writing). But, we can slow down and see what we've modeled and then carefully translate it into math language and equations. Equations are complete sentences containing digits that represent the ideas, operational symbols represent the action [-, +, **÷ **, x] and an = sign. Writing in math language will be clunkier than just using the money and chart alone. Fluency in writing math expressions will come with practice and if the student teaches others how it is done and what the symbols represent.

Again, we start with the concrete and develop fluency in the oral language that describes what we are doing when modeling with bills and coins and discovering relationships with the chart. In human development, we develop speech before the ability to write. After we can fluently discuss ideas and demonstrate them, then we can move to write about them using symbolic math language.

Ultimately, students develop the ability to see the math symbols and associate concrete meaning to them because they have modeled numbers and relationships and have experience translating math symbols into words, and then can combine verbal reasoning and visual reasoning to process quantitative information and solve problems.

When operating at the first stage (verbal and demonstrative), students quickly gain understanding, skill, and confidence.

We anticipate more difficulty when transitioning to the written stage. Just anticipate brain glitches, and just make sure to allow students to restate or rewrite until both words and symbols match the ideas they want to express. Accuracy and ability to integrate doing, describing, and writing in math language, will improve with practice and the student's teaching the process to others.
