Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).
Understanding how our ten number system works enables students to see interesting and useful patterns and relationships in these math activities. These patterns allow students to develop more efficient mental math strategies when multiplying by multiples of 10 or 100. Students will also review rounding and apply this skill to larger numbers - up to 100,000’s place.
Help your child develop their place value superpower with this practice sheet! This worksheet will help your student practice breaking down big numbers into expanded form using place value, from the ones place to the hundred thousandths place.
If you think about math as a language, expressions and equations are the sentences. This unit brings students into the world of “math language”, learning how to write complex expressions in different forms and convert numbers in one form to another (i.e.decimals to fractions). Last, students will apply the order of operations to interpret and solve simple algebraic equations.
The order of operations is a critical concept for fourth graders to grasp in preparation for algebra. This introductory lesson on the order of operations will teach your students about the helpful acronym PEMDAS.
Students familiarize themselves with pre-algebra concepts and vocabulary — including factors, base numbers, exponents, variables, and value — in this introductory overview. This workbook offers plenty of hands-on practice so that students can gain confide
In this worksheet based on the game Two Truths and a Lie, students practice solving three equations and then discussing their findings. Young mathematicians will seek to determine which two equations are true and which equation is false.
