We have used this great tool to compare, add, subtract, and order fractions.  In this picture, we are using the bars to find equivalent fractions. Click here to use interactive bars.

Multiplication

Learning cursive and multiplication are two of the milestones to which the students look forward.  Although I introduced multiplication months ago during our morning equations, I have given direct instruction recently on multiplication vocabulary, concepts, and properties.  The video below is a great review.

Multi-Digit Subtraction

The children have discovered that there is more than one way to find the correct answer in math problems. We learned four different methods to find the difference in multi-digit subtraction problems.  The children really have a deeper understanding of subtraction.

Great Practice

Need something for your kids to do on these cold, wintery days.  I found this great new site:

Room Recess Games

RoomRecess.com is focused on providing children with free educational games. Our games reinforce important skills that are vital to elementary students and their learning process. RoomRecess.com was developed entirely by an elementary school teacher with the goal of reinforcing fundamental learning concepts in math, reading, spelling, language arts, and basic problem solving. Because our educational games are free, students do not have to sign up or hold an account with us. Children can simply load up an activity and have fun learning while they play.”

Geometry and Art

To enrich our geometry unit, Mrs. McGuire (KRCS Admissions Director) shared her love of quilting.  She explained the history of quilting and demonstrated how she designs and makes quilts. So grateful she took the time to share her talents with us!  The slideshow below contains some of the quilts she shared with us.

3D Shapes

We created pyramids and prisms using marshmallows as vertices and toothpicks and stirrers as edges.  This is a great hands-on activity to discover the parts of geometric solids.  We also discovered that shapes constructed of squares and rectangles are much weaker than those made from triangles (a little physics lesson).

Looking for a fun indoor activity?  Give your child a bag of marshmallows and a box of toothpicks and watch their creativity!

Math Talk

An explanation of Math Talk from Math Expressions:

A significant part of the collaborative classroom culture is the frequent exchange of mathematical ideas and problem-solving strategies, or Math Talk.  The benefits of Math Talk include:

  • Describing one’s methods to another person can clarify one’s own thinking as well as clarify the matter for others.
  • Another person’s approach can supply a new perspective.
  • In the collaborative Math Talk classroom, students can and ask for and receive help, and errors can be identified, discussed, and corrected.
  • Math Talk permits teachers to assess students’ understanding on an ongoing basis.
  • Math talk enables students to become active helpers and questioners, that creates student to student talk that stimulates engagement and community.
