# Sr. Cosmas – Third Trimester 2019-2020

Dear Students,
Continue to work hard in your Mathematics, and Religion Classes.
Watch out to see Math spring up in nature around us. We are approaching our 100% last station in June.
Welcome aboard the final coach of 2020 success!

Measurement and Data

• Measurement involving customary units and metric units
• Measurement in volume using cubes, cubic units, and improvised units
• Convert among different-sized standard measurement units within a given measurement system
• Make a line plot to display a data set of measurements in fractions of a unit
• Understand the concept of ratio
• Express ratios in different forms

Geometry

• Define coordinate system using x- and y-axes and locate points on the coordinate plane
• Represent and solve real world problems by graphing points on the coordinate plane and interpreting coordinate values of points in the context of the situation
• Classify two-dimensional figures in a hierarchy based on properties.
• Understand the attributes belonging to a category and subcategory

Geometry

• Find volumes of 3-D figures involving fractions
• Represent three-dimensional figures using nets made up of rectangles and triangles
• Use nets to find surface area in the context of solving real world problems
• Statistics and Probability
• Recognize that statistical questions anticipate variability in the data.
• Understand the distribution of a set of data that can be described by its center, spread and overall shape
• Understand the difference and use of measure of the center of numerical data and the measure of variation.
• Represent sets of data using dots on a number line, dot plots, histograms, and box plots.
• Summarize numerical data sets in relation to their context. Example: number of observations, method and units of measurements, measures of center, variability, patterns, and deviations.
• The shape of the data distribution and context of gathering data drives the choice of measures of center.

Geometry

• Solve problems involving scale drawings of geometric figures
• Describe two dimensional figures resulting from slicing three dimensional figures
• Write and solve simple equations and multi-step problems using facts about supplementary, complimentary, vertical, and adjacent angles
•  Solve real world and mathematical problems involving area, volume, and surface area of 2-and 3-dimensional problems
• Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem solving
• Solve real-world and mathematical problems involving area, volume and surface area of two-and three-dimensional objects

Statistics and Probability

• Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring.
• Collect data on chance process, approximate the probability of a chance event
• Observe the long-run relative frequency; predict approximate relative frequency in a given probability.
• Compare probabilities from a model to observed frequencies, explain discrepancy sources if any.
• Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation

Geometry

• Understand the properties of rotations, reflections, and translations
• Understand and prove congruency between two-dimensional figures
• Understand and describe the effect of dilations, translations, and reflections on two-dimensional figures using coordinates.
• Understand and explain similarities among two-dimensional figures
• Understand the effect of sequence of rotations, reflections, translations, and dilations on two-dimensional a figure and the concept of similarity.
• Understand and explain facts about angle sum and exterior angle of triangles, angle pairs created by parallel lines and transversals

Statistics and Probability

• Display frequencies and relative in a two-way table
• Understand patterns of association seen in bivariate categorical data
• Construct and interpret a two-way table for two categorical variables
• Use relative frequencies to describe possible association between variables.
