Every Friday in Bridges, the students explore the date in many different ways. This provides an opportunity to look at numbers in different ways, composing and decomposing numbers while recognizing the patterns between numbers and their connections to everyday life. Here are two pictures, representing two different Fridays. The first yellow picture, show a connection between the numbers and our calendar grid used in class. We discovered 10 butterflies, 10 praying mantises and 10 beetles on our chart. 10+10+10=30, the date we completed this chart!
We can also write the number 30 as 5x6. WOW, this is 3rd grade math! The students, through visual manipulatives and aids disscovered that we can take 5 six times to make 30! There are, of course, many other connections between numbers and everyday situations. This month, we explored how money can provide us with an example, as seen in the last number sentence. Ask your child to explain how many different number sentences are possible for the number 30 if we use the American coins only. Ask your child if those possibilities differ from all the possible ways we can express 30? Comment on this blog post to share your ideas. Thank you!
This picture represents the beginning half of the calendar grid for the month of October. It is hard to see in this picture, but the first "card" asks the question "Where is the lady bug?". The second question asks "Where is the butterfly?" This month, in addition to finding hidden patterns in our number grids, the students are challenged to use their vocabulary to explain where things are located. We have learned that specific words help us and add details. Mathematicians use VERY precise language. Ask your child to explain.
