![]() ![]() Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3.Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.Understand a fraction as a number on the number line represent fractions on a number line diagram.Lemonade Larry ◊ Multiplication Grand Prix ◊ Greg Tang Word Problems Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = _ ÷ 3, 6 × 6 = ? Determine the unknown whole number in a multiplication or division equation relating three whole numbers.For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. Understand division as an unknown-factor problem.Apply properties of operations as strategies to multiply and divide (Commutative/Associative/Distributive).Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.know from memory all products of two one-digit numbers. Multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations.Rounding Lesson ◊ Finding Place Value ◊ Seashell Rounding ◊ Rounding Soccer ◊ Space Jauntįluently add and subtract within 1000 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.Īdd Up ◊ Addition Flash Cards ◊ Addition Flash Cards (Missing Addend) ◊ Bumble Numbers ◊ Subtraction Action ◊ Subtraction Flash Cards ◊ Subtraction Flash Cards (Missing Number) ◊ Subtraction Soccer ◊ That's a Fact ◊ Shark Pool ◊ Bead Numbers ◊ Place Value Golf ◊ Rounding Spaceships (Nearest 10) ◊ Rounding Sharks (Nearest 100) ◊ The student’s job is to match the flash cards with the answers.Use place value understanding to round whole numbers to the nearest 10 or 100. Write the answers to the flash cards on index cards and scatter them on the table or floor. This is great for moving from concrete to abstract thinking. If the equation is 2 + 3, the student should have a group of 2 items and a group of 3 items. Let them represent the equation on the flash card with the manipulatives. Give the student a flash card, then give them a manipulative such as Legos, candy, or beads. This game is especially good for young learners. Their job is to match up the multiplication card with their corresponding division cards and make math families. Give the student a stack of multiplication flash cards and a stack of division flash cards. Players total up the numbers on their paper and the highest total wins. Each player solves the problems on his or her flash cards and keeps track of their answers on a piece of paper. Divide flash cards evenly between all players. ![]() This is a fun game for more than one student or with a parent and a child. Option: You can use this as a speed drill with 2 or more students competing against each other and have the winner go up one stair. ![]()
