General Activity Information
 Activity ID: 1485 Title: You Kan With Khan: Math Made Easy! Digital Tool/Resource: Khan Academy Web Address – URL: https://www.khanacademy.org/ Overview: Khan Academy is an excellent free resource for differentiating instruction. Students have different learning styles and learn at different levels. With Khan Academy, students can easily and quickly learn complicated mathematical concepts through practice, videos, and examples. Each student can be assigned a different set of lessons depending on their individual level and learning needs. The teacher can decide which lessons a student will work on according to their needs and learning goals. Khan Academy appeals to varying learning styles, provides quick feedback, and allows the teacher to easily individualize instruction.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2015 (2016) Grade: 5 2 ) Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. [5-OA2] Examples: Express the calculation "add 8 and 7, then multiply by 2" as 2 x (8 + 7). Recognize that 3 x (18,932 + 921) is three times as large as 18,932 + 921, without having to calculate the indicated sum or product. Alabama Alternate Achievement Standards AAS Standard: M.AAS.5.2- Select the expression that represents a given calculation (include parentheses). Mathematics MA2019 (2019) Grade: 5 1. Write, explain, and evaluate simple numerical expressions involving the four operations to solve up to two-step problems. Include expressions involving parentheses, brackets, or braces, using commutative, associative, and distributive properties. Unpacked Content Evidence Of Student Attainment:Students: When given a mathematical expression in words, will Write numerical expressions to represent the context and evaluate the expression. Explain their thinking as they use the order of operations to evaluate a variety of problems. Given a numerical expression involving multiple operations and up to two sets of grouping symbols, will Evaluate the expression. Explain the meaning of the expression without evaluating the expression. Note: Expressions should not contain nested grouping symbols, should be limited to expressions found in application of associative or distributive properties, and not always limited to whole numbers.Teacher Vocabulary:Expression Calculate Interpret Evaluate Compare Reasoning Grouping symbol Parentheses Braces Brackets Commutative property Associative property Distributive propertyKnowledge:Students know: Vocabulary associated with the four operations to write the symbolic notation of the mathematical expression. Example: The phrase, "the product of 4 and 3" is written as "4 x 3." Strategies for evaluating a numerical expression and replace it with an equivalent form. Example: Given (22 + 16) + 43 can be replaced with 38 + 43 and then further simplified.Skills:Students are able to: Write, explain, and evaluate numerical expressions representing two-step problems in context. Evaluate numerical expressions with grouping symbols. Translate a numerical expression into words. Write a numerical expression given a mathematical expression in words.Understanding:Students understand that: multi-step word problems can be represented by numerical expressions using operations and grouping symbols to indicate order of evaluating them.Diverse Learning Needs: Essential Skills:Learning Objectives: M.5.1.1: Define parentheses, braces, and brackets. M.5.1.2: Distinguish between non-numerical and numerical expression. M.5.1.3: Recognize expressions. M.5.1.4: Apply properties of operations as strategies to add and subtract. M.5.1.5: Represent addition and subtraction with objects, mental images, drawings, expressions, or equations. Prior Knowledge Skills:Write, explain, and evaluate numerical expressions representing two-step problems in context. Evaluate numerical expressions with grouping symbols. Translate a numerical expression into words. Write a numerical expression given a mathematical expression in words. Alabama Alternate Achievement Standards AAS Standard: M.AAS.5.1 Evaluate simple numerical expressions involving the four operations.
