Here is what the students were working on today. I asked that they take it home and finish it if it wasn't completed in class. We discussed strategies such as using a place value chart or using addition or subtraction when appropriate. For each question, the students must determine the greater value and put the appropriate sign in the bow to indicate greater than, less than or equal to.

We are moving into numeration in Mathematics. Number sense includes skills such as counting; representing numbers with manipulatives and models; understanding place value in the context of our base 10 number system; writing and recognizing numbers in different forms such as expanded, word, and standard; and expressing a number different ways—5 is "4 + 1" as well as "7 - 2," and 100 is 10 tens as well as 1 hundred. Number sense also includes the ability to compare and order numbers—whole numbers, fractions, decimals, and integers—and the ability to identify a number by an attribute—such as odd or even, prime or composite-or as a multiple or factor of another number. As students work with numbers, they gradually develop flexibility in thinking about numbers, which is a distinguishing characteristic of number sense.
https://www.teachervision.com/pro-dev/teaching-methods/48939.html Our introduction to numeration involved finding a way to organize our base-ten blocks in a way that anyone looking at them would know the value of the set. The students knew that ones would have to be made into tens; tens into hundreds; hundreds into thousands; etc. They self organized and cooperated in turning chaos into order, as you can see in the photos below. One of the fun things about learning about light is seeing how color, light and patterns can be used to create images that can be deceptive or misleading to our brains. Below you will find a link to a great website for learning about light and optics. We had fun going through the examples of optical illusions today.
