We have been exploring different ways to represent numbers using place value. Students thought about how to show a number using hundreds, tens and ones. We realized that 10 tens equal 100 and 10 ones equal a 10. We used this to create many different combinations to show the same number!
Second grade teachers attended a professional development seminar lead by Math Specialist Cristina Roof to think about place value activities. One great way to reinforce place value is through oral count arounds! Students started at 312 and counted on by 10s then looked for patterns! We had a great day learning from each other!
Thank you to our amazing volunteers for coming up with fantastic ideas and gathering the materials! Students had an absolute blast making a sign to honor Veterans, gratitude pumpkins and playing fun games! Students learned about a new math tool today- units, rods and flats! We explored the place value tool by constructing buildings. Students then had to think about how many of each kind of blocks did they use? Then they pushed themselves to find the total value of their building! Students discovered connections between the tools. They saw that 10 units fit on a rod and 10 rods fit on a flat. We will use this exploration to launch our next math unit all about place value. Students will learn different ways to represent and organize numbers! Students noticed that the grid in the middle had 100 spots. They saw patterns repeating up- down and left - right in the pieces to the side. They saw some squares with 1 symbol, 2 symbols and only square with 3 symbols. Students figured out that this is a coded 100 chart! They had to look for patterns in the symbols to crack the code. This activity is used to launch our unit on place value! Students will learn how to organize and represent numbers in different ways! They loved cracking this code! Ask your students about how they made their very own code too! See below for the completed 100 chart! Once completed, students began noticing even more patterns! Students then predicted those same patterns would show up in the numbers! Later on we compared them to begin to understand this new math tool!
Students began testing on real life solutions to help prevent soil erosion. We talked about ways to model these solutions in the classroom then began testing! We are using cotton balls to model sandbags, popsicle sticks for a retaining wall, toothpicks for grass and lastly sponges with a bolt to model trees! Students had a blast working together in teams! I am very proud of how they worked together cooperatively! Students observed soil and sand to think about how soil is like sand? Students gathered their evidence to support their claim about how they are similar or very different. Later in our science unit, we are going to use sand as a model for soil so we compare the two to figure out what might work well and what might we need to consider during our experiments. |
