Even & Odd | Rocks | Vactor Truck

This week we explored Even & Odd numbers with a story called "Even Steven and Odd Todd". We then paired students up and discussed how in our class, since we have 24 students, everyone can be partnered up. Even numbers always have a match, and odd numbers always have an "extra" or "leftover" (see number line below).  

This week we learned about the three main types of rocks and how they are formed. We made a model of a rock, by making edible cookie dough. Rocks are made up of several minerals, while a cookie is made up of several ingredients.  Students worked in teams to add the "minerals" to their "rocks".  Rocks go through a process called weathering, where they are altered by wind, heat, and pressure, just as the dough was changed and softened by the students putting pressure on, mixing and stirring the ingredients. 

We had a bonus visit this week from some workers who were solving a sewer drainage issue here at Angell school. We got to see how the Vactor truck worked to suck up sludge.
