Maps: Completed, Evaluated, Appreciated
Last week fourth graders began the task of evaluating each Washington State Map. When students evaluate another person’s work they better understand the importance of looking at grading criteria before, during and in the completion of an assignment. I also started my own evaluations so all maps should go home this week. I am very aware that no score can adequately represent the time and work each map represents. Thank you for all your work. This week fourth graders reflect on their map-making experience – source for insight.
Fourth graders are still planning their journey on the Oregon Trail. Last week we introduced our characters and began our packing lists. This week we plot our route and create wagons. To keep on schedule with all the snow, we will do this in 2D instead of 3D. We will also decide how problems will be solved while on the trail and select a wagon train leader. I will show fourth graders the beginning episodes of “Frontier House”, a PBS reality series that shows modern families committing to living as homesteaders. Check out

Fourth graders are working diligently to fully understand fractions in a deeper level. This week we move forward to the fourth grade textbook, Chapter 6, Fractions and Mixed Numbers. In this chapter, your child will learn about computing with fractions and mixed numbers. Some of the skills include adding and subtracting fractions, converting between mixed numbers and improper fractions, finding a fraction of a set and solving real-world problems.
Finding the fraction of a set or a number is a useful skill with many applications in everyday life. Look out for opportunities to help your child practice this skill. While traveling by bus or car, tell your child that the distance between two points, say your home and school, is 4 kilometers. Ask your child to calculate the distance between the school and another place, say the library, which is half-way between school and home. ½ X 4 = 2 kilometers. I appreciate all the fraction support at home.
