In this activity, students use the Geoboard to determine the length of the sides of a right triangles. [Requires Adobe Reader.]
In this activity, students will explore the properties of rotations and the relationships between the original and image figures.
In this activity, you will explore the invariant properties of rotations and the results of rotations in the coordinate plane.
This activity will help students visualize the construction of congruent triangles and conceptualize properties through measurement and movement of their construction. Students will need access to the TI-84 Plus Family.
Students will use their TI-84 Plus and Cabri Jr to investigate SSS triangle congruence.
Tracking equipment is used to help ship navigators traveling in dense fog determine if they are in danger of colliding with other ships that may be in the area. For this activity, we are going to assume two ships are traveling along intersecting paths. We will develop linear equations that represent the path of each ship and then find the intersection point graphically.
Students study the distribution of sample proportions with a simulation. They find a small sample size leads to skewed distribution and as the sample size increases, the distribution becomes more normal.
This activity is designed to help students discover several important theorems concerning lengths of segments formed by intersecting chords, secants, and tangents.
In this activity, students compare the properties and attributes of different functions.
This set contains questions about simulating sampling distributions. Students see graphs of simulated distributions enabling them to reach conclusions about mean, shape, and standard deviation.
This activity will help students identify the amplitude, period and shifts of graphs of sine and cosine using the TI-Navigator.
This StudyCards set begins with "what is an equation?" and continues to the meaning of solving an equation. The function approach is used to solve the equations.
Students will solve systems of linear equations by a variety of methods: graphing, substitution, and elimination. The questions are multiple-choice and fill-in-the-blank.
This activity is designed to assess the comprehension of concepts related to solving equations, literal equations, and right triangle trigonometry.
This set contains statistics questions regarding experiments and experimental design. The student becomes familiar with the various elements of experimental design.
Students perform single and two-sample t procedures to investigate special cases of normally distributed data. They explore inference for a least-square regression line, including the confidence interval.
What types of statistical graphs are there and when and how are they used and read? How are statistical graphs used in Economics?
Students will determine the mean, median, mode and standard deviation of collected data. They will make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+.
Students understand statistical concepts like center of data and the amount of data variation from the center. They calculate the measures of the center of a distribution and the measures of spread for the data collected as a list. Students also create box plots for the data. They examine the effects of changing units on summary measures.
In this activity, students use the Geoboard to determine the area of triangles using the surrounding rectangle technique. They also develop and use formulas to determine the area of triangles. [Requires Adobe Reader.]
