April Fool’s Day Problem of the Day

Today we are going to take a short break for the typical problem of the day. The first of the April Fool’s Day problems is appropriate for all age groups. The second will test your knowledge of Algebra so is best left to 8th graders and above. I hope you enjoy these brain teaser math tricks. 

 

Problem 1

Write down a three digit number. The first and third digits must differ by more than 1.      735

Reverse the digits to form a second number.        537

Now subtract the smaller number from the larger.   735 - 537 = 198

Now reverse the digits in the answer you got in step three and add it to that number.    198 + 891 = 1089

Multiply the number by 1 million    1089 X 1,000,000 = 1,089,000,000

Subtract 733,361,573 from that number

1,089,000,000 - 733,361,573 = 355,638,427

Under each of the digits in your answer, write the letter which corresponds to it using the...

How to Keep Your Student on Track During School Closures

Uncategorized Mar 16, 2020

Each day the news brings more unprecedented closures including our schools. How can you help your student stay on track, or maybe even gain ground during this time? 

Fortunately, many students are already familiar with some form of online learning. The challenge is to help them stick to a schedule. We all do it. We get an unexpected snow or hurricane day and all we want to do is relax and enjoy. This closure is different. It isn’t a day to two. So far in Florida we are looking at two weeks and there is a very real possibility that it may be longer than that. 

It is critical that your student continue as though he or she was still attending school. Set up a work area and time expectations. Be specific! Don’t just say, “Go do your schoolwork.” Help them set expectations for how long assignments will take and prepare a schedule from there. I find it helpful to set time blocks rather than task completion. For example:
