With clear illustrations and narration, the lessons in LearnZillion: 4th Grade Math are an effective way to address Grade 4 Common Core math standards. Many of the lessons include coach's commentaries and guided practice videos. The coach's commentaries can help you prepare for a lesson with information about prerequisite skills, common misconceptions, and teaching tips. The guided-practice videos give kids an opportunity to try a problem on their own before viewing the solution.
Overall, these lessons are best used as supplements to your classroom instruction. To use them most effectively, first view the coach's commentary, if it's available. Then, review the prerequisite skills out loud with the class to give kids a sense of where they're starting. Have kids view a lesson in small groups before coming back together to discuss the lesson. Last, have kids do the guided practice problem, working independently if possible. If the lesson doesn't have a practice problem, have kids write their own and exchange it with a partner to solve.Continue reading Show less
Key Standards Supported
Number And Operations In Base Ten
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
Use place value understanding to round multi-digit whole numbers to any place.
Number And Operations—Fractions
Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Operations And Algebraic Thinking
Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1
