Math

Fractions!  Everyone is learning about fractions!  WooT!  4^th graders are learning more about equivalent fractions and have just started learning about tenths and hundredths and how to write both decimals and fractions.  We are using fraction circles (or rectangles) and number lines a LOT.  Learning to divide things into equal parts has been our focus in the last few days.  

Here’s a math message from last week: 

Ten preschoolers shared 2 liters of fruit juice equally during morning snack.  How much juice did each student get? 

5^th graders are also working with fractions.  They learned that conjecture is a prediction based on mathematics, and will be used throughout this unit.  

Here’s a math message from last week:

Christopher solved 2/3 + 1/2 and got 3/5.  Sam said “I think your answer is wrong and I can prove it without calculating.”  Show how Sam can prove that Christopher is wrong without calculating a solution.
