Mrs. Landas' kindergarteners were practicing their addition and subtraction strategies within ten through the "Bowl Game." In this game, a duo starts with ten Unifix Cubes. One partner covers their eyes while the other "hides" some under a bowl. The partner who did not look figures out how many are there and how many are under the bowl.
Mrs. Landas extended the "Bowl Game" by giving the option to write addition or subtraction equations to match the thinking involved in playing the game.
Mr. Welton's third graders explore skip counting with Unifix Cubes. They compare their skip counting number lines to others and one group even suggests to "Measure Mr. Welton!"
Mr. Welton's class looks at the Calendar grid while they look for patterns to predict what the next array will be.
Ms. KM's fourth grade students explore division through arrays with base ten pieces.
Second graders at Brooklyn in Mrs. Kluck's room learned what a century was and practiced counting by tens until a century. They will keep practicing this until they make it to a millennium.
First graders at Netherwood in Mrs. Harbort's room were looking for patterns in the calendar during Number Corner. Number Corner is a Bridges component that is explored in a classroom community meeting style. Every day, the class updates the calendar and looks for patterns.
In upper grades, students practice Problem Strings. Each problem string starts with an easier problem to practices strategies and then gets more difficult to practice efficient strategies in a challenging way. At Netherwood, a student in Ms. Bestul's fourth grade class class explains his thinking during a Problem String.
Another child from Ms. Bestul's class showed his thinking through an area model in a different way as shown below.
