How to Keep Score in Bowling – A Real-life Application of Following Directions and Addition Skills Back in the “old days”, people who bowled at the bowling alley were given a paper score sheet, and it was up to them to keep score to determine the winner of the game. Today the scoring is all done by computer, and if one can read the numbers on a monitor, one can determine who won the game. Most young people today do not have a clue about how to keep score in bowling. This resource is designed t

Every math teacher knows that basic math fact fluency is critical to student success in any math procedure involving computation. The goal I have for my students is that they know the basic math facts on sight as well as they know the letters of the alphabet. After students have had ample time to practice the facts, I give an assessment to determine which students have mastered them. Those students who are not yet up to speed then begin participating in my weekly math fact plan. This plan
