The directions on how to help children develop proportional reasoning include all of the following statements EXCEPT
Provide ratio and proportion tasks in a wide variety of contexts
Encourage discussion and experimentation in predicting and comparing ratios
Help children relate proportional reasoning to existing processes
Teach dependence on an algorithmic procedure such as the cross-product algorithm
A ratio is defined as
actually more like a fraction than a decimal value
a fraction that actually refers to parts of a whole
is only part of a proportional situation
a multiplicative comparison of two numbers or measures or quantities
Ratios can be all of the following EXCEPT
An expression of a rate
A probability of an event
A comparison of two parts of the same whole
An equality of two fractional numbers
When exploring the different opportunities for developing proportional reasoning, all of the following categories of proportional activities should be explored EXCEPT
construction and measurement activities
solving for the unknown activities
selection of equivalent ratios activities
scaling with ratio table activities
All fractions are ratios because they both can be a comparison of parts-to-wholes.
The cross-product algorithm should be introduced early along with many intuitive, conceptual methods.
All graphs of equivalent ratios fall along a straight line with slope = m and the equation is y = mx.
Proportional reasoning includes a sense of covariation, a recognition of proportional relationships, the development of strategies for solving proportions or comparing rations, and an understanding of ratios as distinct entities.
Explain the difference between a ratio and a proportion.
