It’s Wednesday – here are some problems to solve

numbersLast week when we took our basic fact test there were two people who were proficient  with addition.  That means getting at least 68 of the 70 problems correct and doing them in 5 minutes or less.

11 people in our class are working to meet that expectation with addition.  We also have to work on the same level of proficiency with subtraction and multiplication this year too. I hope you’ve been finding ways to practice and improve.    Here are a few ideas and some problems that might help.  Keep up the great work.

2-Digit Addition Split may be a good way for you to practice some facts and also learn how to use expanded notation to organize your math thinking.  Click on the name and it will take you to the directions and show you how to do it.  You can bring your work to school or you can post your work in a comment.

If you’re in the mood for some addition puzzles try some of these Magic Squares.  Again, you can bring your work to school or share your work in a comment below.  You can type your answers in a three by three pattern.

How many different 3-digit numbers can you make using the digits 1, 6 and 9?  Order the numbers.  What is the difference between the smallest and largest number?

Liam added two three-digit numbers and got a correct answer of 748.  What might the two numbers be?

Which is larger:  1/4 or 3/8?  Explain your reasoning.
