Grade 5 Math
The Acellus Grade 5 Math course is designed to give students additional experience with basic mathematical operations (addition, subtraction, multiplication, and division). Besides working with larger whole numbers, in this course students focus on performing these mathematical operations on fractions, mixed numbers, and decimals. Students are introduced to basic algebraic and geometric concepts and many other topics to provide them with a strong mathematical foundation.
Course Objectives & Student Learning OutcomesUpon completion of Acellus Grade 5 Math, students will be able to: add, subtract, multiply, and divide with tenths, hundredths, and thousandths place for billions and decimals; compare and order decimals; converting decimals to expanded form; use mental math using the commutative and associative properties; round whole numbers and decimals; estimate whole number and decimal sums and differences; and solve word problems. Students will also be able to use multiplication properties and mental math to estimate product and multiply 1-digit and 2-digit numbers by greater numbers; divide tens and hundreds; estimate quotients; use reasonableness; divide by 1-digit numbers and quotients with zeroes; use division strategies, estimate quotients with 2-digit divisors; divide by tens, quotients with 1-digit and 2-digit numbers and decimals; estimate and divide greater numbers; solve word problems; use algebraic variables and expressions, operations order, brackets and numerical patterns to solve problems; multiply decimals by powers of ten, exponents on ten; and estimate products of decimals, whole numbers and decimals, and decimals by decimals. Finally, students will be able to divide decimals by powers of ten and by power of ten using exponents; estimate quotients involving decimals, of decimals and whole numbers; with decimals; divide decimals by whole numbers, decimal divisors, and dividends; solve word problems; measure and classify angles of 2-dimensional shapes; convert fractions and decimals; add, subtract, multiply, and divide fractions and mixed numbers; measure and convert customary and metric units of measurement; and solve problems using line plots, ordered pairs, graphing, interpreting patterns, and comparing graphs.
