In math, second graders are building an understanding of repeated addition, a necessary precurser to understanding multiplication. In this problem, students created a box of candy, in an array, or a rectangle with rows and columns. The repeated addition equations below the array show the student understand how to efficiently determine the total number of candies.
With the help of Mrs. Sweet, the second grade students created their own maps of Morris. We used a printed map, as well as google maps, to identify the shape of our town, the major bodies of water, including Bantam Lake and Bantam River, and the major roads. Students then replicated the map freehand, using the shapes and sizes of the identified markers as reference. What a great way to learn more about our town, how to read a map, and visual/spacial reference. We will be sharing some of the maps at the upcoming Celebration of Learning.
Second graders have been reading biographies, focusing on character traits and accomplishments people are known for. After reading and taking notes about famous people, they are designing their own projects to present their information. They are hard at work planning, designing, creating, and improving their projects. We can't wait to share the final products!
Second graders have been reading nonfiction topics across multiple books. Working in groups, they learned all they could about a topic, such as sharks, plants, dinosaurs, bats, or space. Groups then created posters to teach others what they learned. The groups presented their informational posters to the third graders recently. The second graders are eager to tackle this type of project again. Upon reflection of the poster and presentation, almost every student said they would practice more to be confident and comfortable with what they will say. Growth mindset at its best!
Second graders are exploring three digit numbers in many ways. We created these animals using hundreds, tens, and ones. Then we determined the total number by adding the parts. Students know how to represent three digit numbers in standard form, expanded form, word form, in a drawing, and on a number line. Next, we are learning to compare three digit numbers by using the symbols: <, =, and >.
Pablo and the second graders love using this math target that Mrs. Leonard created. When they hit the target with a tennis ball, the numbers rotate. When the spinning stops, we read the new three digit number that was created. The second graders are learning how to add and subtract 10 and 100 to the three digit number. They are also learning to write the three digit number in many ways: in standard from, word word, and expanded form. The math target makes math even more exciting than usual!
Second graders have been working on ways to organize data in math. You can see by our class chart, there are lots of vocabulary and visuals to learn and use! First, when collecting data, you might take a survey, or ask a question with given choices, and then organize the the information. We have been organizing the responses to a survey in a table, as seen in the upper left corner of our chart. Then, we could make a line plot, pictograph, or bar graph of the information. Finally, we need to understand the information on the graph. We have been finding the difference between two responses and determining how much more than or less than another answer it is. When you find a table or graph at home in the newspaper, magazine, or book, you could read it and talk about too!
Pablo and the second graders have been learning a lot of new words to describe properties of matter, like absorbent, insulating, conducting, and opaque. We all had fun with the experiment this week to figure out which candies are meltable. We found out that chocolate is fully meltable, gummy bears and starburst are partially meltable, and jelly beans are not meltable. This helped us understand why plastic is such a great material to make things out of. Plastic is meltable! It can be poured into a mold so the items can be easily reproduced many times.
Pablo is also excited about a new app we are using called Seesaw. Students can post videos, pictures, drawings and notes to explain what they are learning. Parents, be on the looked out for a notice next week about signing up for Seesaw. Then you can see what your child is posting and learning at school!
This week we did an experiment to test which materials are the best insulators. We wore different materials, aluminum foil, cloth socks, and styrofoam cups, on our hands, like mittens. We touched a warm water bottle and a cold water bottle with the different materials. We figured out that the styrofoam is the best insulator and the aluminum in a conductor.
This week in second grade we started a number of new learning units. In writing, we are working on information writing. We will be learning about how to organize writing into chapters by topics, how to use facts and keywords in our writing, and how to use diagrams to explain information too. We are also reading about nonfiction topics, learning how to use the text structure, like the table of context, graphic aids, key words and glossary to understand what we are reading. We are also practicing fluency by rereading paragraphs out loud. In math, we are starting a measurement unit. We are measuring items in the classroom in inches and soon, in centimeters. We are also finding the difference between the length of different objects. You could practice measuring items at home too!
