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.

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.
