Transcript

  • 1. We want to show you a little bit of the work we’ve been doing. Click the mouse when you’re ready for the next slide. Ready? Go! Keep clicking.
  • 2. Area Puzzler Can you make a square shape with an area of 200 square units?
  • 3. We’re trying … Hold on. We’re still trying. We don’t think it’s going to work, but we’re still trying.
  • 4. Area Puzzler We tried and tried. It turned out to be a rectangle, not a square. Interesting.
  • 5. Multiplication Practice! We use beans as counters to make arrays to figure out answers. We can’t use counters on the TAKS test so we have to be able to draw the arrays, also. It’s easy because we’re Amazing Mathematicians!!! Factor X Factor = Product (# of rows) (# of beans in each row) (Total # of beans)
  • 6. We folded a piece of construction paper and cut on the folded side. When we unfolded it, we revealed our design. Some of them are funny! We had fun!
  • 7. Look at mine!! Did you find it? Did you see the line, or lines of symmetry? Look again.
  • 8. We’re learning all about 2-D and 3-D shapes. We have to name, describe, and compare shapes and solids using formal geometric vocabulary, identify congruent shapes, create shapes with lines of symmetry using concrete models and technology, and identify lines of symmetry in shapes. We have to use linear measure to find perimeter of a shape, and use concrete models of square units to determine the area of shapes.
  • 9. We’ve learned about fact families and that if we know a multiplication fact, then we know the division fact. But we still need to use models to understand what we’re doing. We use our “bean bags” with the blue stick kids you will see in the picture to divide a certain number of beans equally between the given number of kids. Dividend ÷ Divisor = Quotient (# of beans) (# of kids that share them) (# of beans each kid gets)
  • 10. ROUNDING!!! Remember when we brought home the roller coasters called “The Estimators?” The next three pictures show rounding to the nearest ten, hundred, and thousand.
  • 11. As you can see, there’s a lot of learning going on!!! Now ask us what we did at school today! We’ll show you!!!
