What is the decimal model?
Model Decimals The use of a decimal point is a symbol that separates the tenths from the ones, or the 'part from the whole'. For example, in the number 4.2, the decimal point separates the 4 ones and the 2 tenths. The base ten place value system is built on symmetry around the ones place and the decimal.

What is a visual fraction model?
visual fraction model. • a visual model showing a fraction or fractions.
What is a area model?
In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle.
What is a region model?
The regional model simulates migration and distribution of overall growth or decline of population and employment in different economic sectors. It is based on a spatial interaction or gravity model operating on a regional scale.
What are the three major categories of fraction models?
The three major categories of fraction models are the area model, linear model, and set model. Evidence suggests that providing opportunities for students to work with all three models plays a crucial role in developing a conceptual understanding of fractions. Having students repeat an activity with a different model and asking them ...
What is a fraction strip?
Fraction Strips can be used to explore equivalency, comparison of fractions, ordering fractions and number operations with fractions. If purchasing commercially made strips opt for those that are unlabeled to provide more opportunities for thinking and learning. Sample Activities: Making Fraction Strips (ver. 1)
What are the manipulatives used in area model?
Useful manipulatives include rectangular, or circular fraction sets, pattern blocks, geoboards and tangrams.
What is set model?
3. SET MODEL: In the set model the whole is understood to be a set of objects, and subsets of the whole make up fractional parts (e.g. ½ of the class, ¼ of a set of buttons, 1/3 of a tray of muffins). Useful manipulatives include two-color counters, centimeter cubes, or any set of objects that can be counted (e.g. a bag of marbles).
How many shapes are in a Tangram?
The standard tangram consists of seven shapes that can be arranged to form a square. Frequently used for exploring geometry, they can also be used for problem solving tasks involving fractions. Sample Activity: The Warlord's Puzzle.
Why is the number line important?
The number line is an important linear model for students to work with as it reinforces the fact that there is always one more fraction to be found between two fractions. Sample Activities: Fractions on a Number Line. Roll a Fraction.
Fraction Models
Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models. Adjust numerators and denominators to see how they alter the representations and models. Use the table to keep track of interesting fractions.
How to Use
Adjust the value of the numerator and denominator by: moving the slider, using the + or – on either side of the sliders, or entering the values directly in the boxes.
Exploration
Adjust the numerator and denominator at the bottom to change the fraction. What is the result? How does the result relate to the values shown for mixed number, decimal, and percent?
What is a fraction in a linear model?
A fraction is identified as being a particular distance from the 'start' of the whole.
Do fractions represent the same quantity?
Placing fractions on a number line use s a similar approach, but highlights the fact that some fractions occupy the same position on a number line and therefore represent the same quantity. Visualising equivalent fractions.
What is the best model for fractions?
One useful model for fractions is the liner model. In a linear model, the whole (or unit) is represented by a specified interval on a number line. Then fractions are represented as lengths of intervals in comparison to the length of the whole.
What is the third useful model for fractions?
third useful model for fractions is the set model. Set models are based on numbers of objects in a set, not their area. For example, in this diagram, 2 of the objects are circles and
What is improper fraction?
The term improper fraction is used to describe fractions greater than one. Identify the statement that is true about the term improper fraction. A) Is a clear term, as it helps students realize that there is something unacceptable about the format. B) Should be taught separately from proper fractions.
What does "d" mean in math?
Answer: D) A unit or length involving fractional amounts.
Is it difficult to find fractions on a number line?
Locating a fractional value on a number line can be challenging but is important for students to do. All of the statements below are common errors that students make when working with the number line EXCEPT:
What is a fraction bar model?
A fraction bar model is where you draw a long rectangle and divide it into equal parts to show a fraction. 📣 The denominator is how many equal parts you should divide the bar into. 📣 The numerator tells you how many parts to color. Here are bar models for some unit fractions. 😸. Tip: unit fractions have 1 in the numerator.
What are some examples of fractions?
Fractions are parts of the whole. 👉 Some examples of fractions are 1/2, 1/4, 2/3, and 3/4. The number above the fraction bar is called the numerator . 👉 It describes the number of parts you have. The number below the fraction bar is called the denominator.
What is the denominator of fractions?
Because fractions are parts of a whole, they go somewhere between 0 and 1 on the number line. 📣The denominator tells you how many equal parts or segments to divide the line into . 📣The numerator tells you how many parts or segments must be colored. Here are number line models for some unit fractions. 😸. It's almost the same as the fraction bar ...
