Current Math Focus November 2019 We are finishing up our work in the Number System Unit. Students have learned how to divide fractions, how to add, subtract, multiply & divide decimals, how to find the GCF & LCM of two numbers, how to convert rational numbers, place them on a number line, compare them & how to use all four quadrants on a coordinate plane. Once students take their Number System test, we will begin exploring beginning ratios in the Ratios & Proportions unit.
