Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent.
Use fraction models and hundredths grids to identify equivalent fractions, decimals, and percents.
Factor and expand expressions like -3x-9 by applying the distributive property. Expressions include variables and negative numbers.
Practice solving equations that take two steps to solve. For example, solve -16 = x/4 + 2.
Practice interpreting and comparing dot plots, histograms, and box plots.
Practice solving addition or subtraction word problems using a number line. All items include 4 two-digit numbers.
Given a graph of a parametric surface, what equation created it? Or, given an equation, what is its graph?
Practice identifying when slope or intercepts are useful for answering questions about a linear relationship.
Create and interpret picture graphs. Each picture on the graph represents a number greater than 1.
Given the formula of a sinusoidal function of the form a*f(bx+c)+d, draw its graph.
Compare two fractions that have the same numerator using greater and less than symbols.
Compare two fractions that have the same denominator using greater and less than symbols.
Solve word problems that involve converting between metric measures of distance, volume, and mass, as well as measures of time.
We can describe the trigonometric ratios from a single right triangle in terms of either acute angle. The relationships hold for all complementary angle pairs.
Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
Use area models and tape diagrams to multiply a fraction times a fraction.
Solve fraction and mixed number multiplication word problems.
Interpret bar graphs to answer questions about a context.
Let's try to associate the condition of collinearity with a mathematical result and hence use it to find the unknowns.
Solve 1-step word problems involving metric units of measure and time.
