Essential Learning Targets 8th Grade Math Core ELT One: Know numbers that are not rational, and approximate them by rational numbers. ● I can recognize irrational numbers. ● I can see that all numbers can be written as decimals. ● I can use rational approximations or irrational numbers to compare irrational numbers. ELT Two: Work with radicals and integer exponents. ● I can know and apply the properties of integer exponents. ● I can evaluate square roots of perfect squares. ● I can use powers of 10 to estimate very large and very small quantities. ● I can perform operations with numbers in scientific notation. ELT Three: Understand the connections between proportional relationship, lines and linear equations. ● I can graph proportional relationships. ● I can interpret the unit rate as the slope of graph. ● I can use a triangle to show the slope is the same between any two points. ELT Four: Analyze and solve linear equations and pairs of simultaneous linear equations. ● I can solve linear equations. ● I can combine like terms. ● I can use the distributive property. ● I can use a graph to understand the point of intersection for two equations is the solution. ELT Five: Define, evaluate, and compare functions. ● I can identify a function from a table and identify a function from a graph. ● I can compare functions as linear or nonlinear from an equation. ELT Six: Understand congruence and similarity of figures. ● I can verify that lines, line segments and figures remain congruent through rotation, reflection and translation. ● I can describe the transformation as a rotation, reflection, or translation. ● I can understand that any combination of transformation (rotations, reflections, translations, dilation) will result in similar figures. ● I can understand the relationship of angles in triangles and when a set of parallel lines is cut by a transversal. ELT Seven: Understand and apply the Pythagorean Theorem. ● I can explain a proof and the converse of the Pythagorean Theorem. ● I can apply the P. Theorem to find unknown side lengths in right triangles in real world problems. ELT Eight: Solve real world and mathematical problems involving finding the volume of cylinders, cones, and spheres. ● I can learn and use the formula for volume of a cone, cylinder and sphere. ELT Nine: Investigate patterns of association in bivariate data. ● I can construct a scatter plot for two variable data. ● I can describe clustering, outliers, and correlation in scatter plots. ● I can informally draw a line of best fit. ● I can construct and summarize data from a two­way table.
