Last week we started a new mathematics unit focused on algebraic thinking. Although algebra has been considered a subject for upper grades, the work we are doing now builds a solid foundation for later years. Research shows that introducing very young students to algebraic ideas sets the stage for later success!
We began with a discussion about the number zero. The students shared their ideas about zero and raised questions they have about zero. Tonight, your child will ask you what you know about zero. After you share an idea or two, ask them what they know or wonder about zero. Tomorrow, the students will share the ideas from their families, and we will add any new information to our class charts, “ Our Ideas About Zero” and “What We Wonder About Zero.”
Over the next few weeks, our math work will focus on the important role of zero in our base ten number system as well as some of the special properties of zero. For example, they will learn that any number plus zero is equal to that number (0+n=n) and n+0=N), known formally as the Identity Property of Addition.
We will also compare numbers and use number lines for addition and subtraction problems. The students will solve problems with an “unknown” and use the notation for equations and inequalities. Computational strategies will also be introduced.
Be sure to ask your child what we are doing in class and please come into our classroom to read our charts and check the “What We Learned” chart for additional updates.
