Overview:

This single-part task illustrates what problem solving means in the CCSSM. Although there are many entry points into this problem, students must analyze constraints, relationships, and goals to find all possible solutions. They formulate a solution pathway rather than jump into a solution attempt.

Overview:

Students can solve the problem using a variety of approaches. Logical mathematical reasoning, rather than reliance on rules, leads to a solution. In Part a, students demonstrate their understanding first by analyzing a visual model to determine a fractional area; they are then asked to determine an equivalent fraction in order to represent that number on a number line. Parts b and c require students to think about fractional representations in different ways and recognize representations that are unlike those they may have traditionally seen. In so doing, students reason abstractly and computationally.

Overview:

This five-part task illustrates the important CCSSM shift to consider fractions not only as parts of a whole, but also as numbers that can be located on a number line. This latter meaning helps students develop an understanding of the structure of fractions within the number system and builds an important foundation for using number properties and developing operations with fractions.

Overview:

Students explore dilations of lines by selecting points along the line and thinking about point-by-point dilations. Students connect to the definition of a dilation using ratios. The dynamic nature of the animation allows students to explore a variety of situations, including the location of the center of dilation with respect to the line and the scale factor used. Students discover that, if the center of dilation is not on a line, the dilation of that line is a line parallel to the original line.

Overview:

Part B addresses student understanding of the concept of rate of change within the provided context. This item uses a machine-scored, multiple-choice format that requires students to select all correct answers from the set provided. This is designed to elicit deeper analysis than a traditional single-answer, multiple-choice format.

Overview:

Students consider the relationship between the volume of air in a person's lungs over time as they breathe. Students look at a graphical model and describe key features of the graph. Students notice that the shape of the function is different from the linear, quadratic, and exponential functions they have studied previously. This motivates the need for cubic functions.

Overview:

Students are introduced to the concept of the residual. They use a regression equation to compute the values of the residuals for a set of data and see how residuals can be understood by drawing error lines connecting each point in the scatterplot of the data to the residual line. Finally, they plot the residuals and see how their distribution relative to the x-axis can be used to assess the quality of the fit of the linear model.

Overview:

Students use transformations to show two triangles are similar. Students can use Patty Paper or MIRAs to work in small groups to find a sequence of transformations that will map ABD onto DEF. The key is for students to recognize the need for a reflection and dilation. Once students have found a sequence of transformations, they should develop a viable argument to share with other small groups. As student groups share their arguments, they should be encouraged to use precise language about the transformations and similarity.
