Today we reviewed criteria for shapes to be polygons and for shapes to be regular polygons. We then moved into classifying triangles based on their sides (equilateral, isosceles, or scalene) or based on their angles (acute, right, or obtuse). This is a challenging topic for students to keep straight. Often they will not pay attention to which way they are meant to classify. We will keep practicing this as we warm up for future lessons.

Today we used an online simulator to determine the concentrations of different solutes. Students were able to play around with different types of solutes and different amounts of water. Students also played around to discover how evaporation and adding more solvent affect the concentration of the solutions they had made. Students used this link to get to the online simulation....you may want to give it a try too :)
Today we watched a few short videos to review chemical changes and the conservation of matter (chemical changes and lego block party). Students took notes and we reviewed the ideas using our classroom experiments.
Today we started class by practicing converting between different units of length (ex: inches to feet). Then we moved into identifying shapes based on sides and angles. We reviewed the criteria for shapes to be polygons and introduced the idea of regular and not-regular shapes.
Homework tonight: complete pages 907 and 908 from the text book Today we reviewed what evidence pointed to a chemical change taking place. To demonstrate that some chemicals are more reactive than others we again put together baking soda and calcium chloride and baking soda and citric acid. This time, however, we did the experiment with ziploc bags so that we could capture the gas that forms. Students found that the solution with citric acid created much more gas than the one with calcium chloride.
Today we took the comparing/ordering fractions quiz. Tomorrow we start our geometry unit.
Today we discovered that our solution from last week created salt as a chemical change product. We identified the crystals and talked about how chemical changes rearrange the elements of materials to form new products. We compared this to building with legos (taking apart what we started with and creating new objects with the same pieces, just mixed around)
In my notes I used color to show where the different pieces go. Today students practiced using common denominators to put fractions in order. We did a mini-lesson reviewing how to find common denominators by using the largest denominator and running through the multiples until they find one that works for all denominators. Some students finished their practice in class and worked on a review of comparing, reducing and converting improper fractions into mixed numbers.
Homework: finish the work started in class (ordering worksheet or review worksheet) QUIZ tomorrow on comparing and ordering Today we moved from comparing simple fractions to comparing mixed numbers. Students finished up with their homework worksheet from last night and the worked on more comparing and reducing practice.
Work to complete: Today we discussed and practiced several different strategies for comparing fractions. Students completed at least one problem from the board and created one problem for each for of the 5 strategies that we discussed. Students tend to want to use the "butterfly method" which is a short cut on finding common denominators.
Homework tonight: Page 77 worksheet- numbers 1-24 only. **Show work if both numerators/denominators are not common** |
