Fifth Grade Big Idea 2 Day 2 Develop an understanding of and fluency with addition and subtraction of fractions and decimals.

The Importance of Decimals….

Roll to a Whole Directions: Roll a number cube to see who goes first. Player 1 rolls a number cube and places the digit shown in either the tenths or hundredths place. Player 2 now repeats the same procedure. The game continues until each player has 5 rolls. Each player now finds the sum of his or her 5 rolls. The winner is the player with the sum closer to 1.0 without going over the 1 whole.

MA.5.A.6.5 Solve non-routine problems using various strategies including “solving a simpler problem” and “guess, check, and revise.”

Problem Solving  Problem Solving is a complex and critical topic in mathematics education, the National Council of Teachers of Mathematics recognizes it as the central focus of the math curriculum.  Students need time to explore, discuss and reflect on problem situation.  Thinking strategies help students to organize information, recognize relationships between numbers, effectively draw conclusions, and provide a path to move towards a solution.
