These are some of the subtraction strategies we've been working on in class.


In math we've been learning about how to represent 3-digit numbers in many different ways.  We studied expanded form with these manipulatives.  They show us that numbers can be split into hundreds, tens, and ones.  For example, 376 written in expanded form is 300 + 70 + 6.  This skill will help us when we are adding and subtracting 3-digit numbers.  

We just finished up a science unit about rocks.  We used this rock sample kit to look for rock features such as crystals, layers, cement, and different sizes of grains.  We noticed common traits of igneous, sedimentary, and metamorphic rocks.  We learned that small rocks come from big rocks that have broken apart.  

We learned that almost all fiction stories have one or more characters, settings, problems, and solutions.  Look for these story elements when you are reading with your child.

We read Frog and Toad this week and made puppets to act out the story.
