One of the best ways to have a deeper knowedge of math is to have discussions about it. "Decimal True False Sort" gives the students the opportunity to discuss solving deciamal problems (addition, subtraction, division, and multiplication included) while deciding which statements are true and which are false. This is a great Common Core activity that incorporates many of the Standards for Mathmatical Practice.
Example statments include: "When dividing decimals, your divisor may not have a decimal", "10 - 1.234 = 8.766", and "it is ok to use a decimal and a remainder for one answer".
Battleship and Angry Birds:
Students pair up (one getting board A, one getting board B)
The questions on Board A have answers on the bottom of board B (and vice-versa). Students take turns solving a problem and telling their partner an answer. If the answer is on the ship (or bird), its a hit! If the answer is around the ship/bird (in the water), its a miss! The first person to sink their opponent's ship/hit all birds is the winner.
Students pair up and share one game board. They then choose a question to complete- whomever gets the question correct marks off the square with the corresponding answer (if both students get it correct, they pay rock-paper, scissors to decide who marks off the square- which is their favorite part!)
