Gwinnett County Academic Knowledge and Skills
AKS: 8.OA.8 solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
· AKS: 10.OA.9 identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operation (e.g., observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends)
AKS: 32.MD.5 recognize area as an attribute of plane figures and understand concepts of area measurement.
· AKS: 33.MD.5_a. use words, pictures and/or numbers to show that "unit square" is a square with a side length of 1 unit, has an area of one square unit, and can be used to measure area of plane figures.
· AKS: 34.MD.5_b. demonstrate that a plane figure which can be covered without gaps or overlaps by "n" unit squares is said to have an area of "n" square units.
· AKS: 35.MD.6 measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units)
· AKS: 36.MD.7 relate area to the operations of multiplication and addition.
· AKS: 37.MD.7_a. find the area of a rectangle with whole-number side lengths by tiling it and show that the area is the same as would be found by multiplying the side lengths.
· AKS: 38.MD.7_b. multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real world and mathematical problems and represent whole-number products as rectangular areas in mathematical reasoning.
· AKS: 39.MD.7_c. use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a x b and a x c; use area models to represent the distributive property in mathematical reasoning.
· AKS: 40.MD.7_d. Recognize area as additive; find areas of rectilinear figures (polygons all angles of which are right angles) by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
AKS: 29.MD.3 draw a scaled picture graph and a scaled bar graph to represent a data set with several categories; solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs (e.g., draw a bar graph in which each square in the bar graph might represent 5 pets)
