In our listening and learning strand we are studying the human body. We read about Anton van Leeuwenhoek, a Dutch scientist who discovered bacteria more than 400 years ago. We learned that Anton van Leeuwenhoek kept detailed journals about his discoveries, which is how we know about his work today.
Also, we learned that the smallest microscopic building block of all living things is the cell. We found out that tissue is a multiple meaning word. While we might use a tissue to blow our nose, tissue can also be a group of cells doing the same thing. We combined four different colors of tissue paper to represent the epithelial, muscle, nervous, and connective tissues. Then we used these tissues to complete a drawing of a cross section of a human stomach.
We learned that cells make up tissue and that tissue makes up organs. We found out that the human body has many organs that perform certain vital functions that make the whole system work. Ask your child what is the largest organ in the human body.
In math, we wrapped up our unit on place value. We learned how to model 1 more and 1 less, 10 more and 10 less, and 100 more and 100 less using place value disks. In addition, we did the same modeling using language to tell about 1 more and 1 less, 10 more and 10 less, and 100 more and 100 less. Practice with your child by asking questions such as “What is 10 more than 190?” Have your child answer in a complete sentence such as “200 is 10 more than 190.” Try this with other three digit numbers using 1, 10, and 100 more as well as 1, 10, and 100 less.
Finally, we studied number patterns and created patterns with numbers counting up and counting down. The Module 3 math assessment is in your child’s Friday Folder. Please look for it to see how your child is doing.
Next week we will begin to study addition and subtraction within 200. Strong knowledge of math facts will be necessary for this module. We will use the place value strategies that we learned to fluently add and subtract and develop students understanding of addition and subtraction of multi-digit numbers within 200.
