Christmas Candy Cane Estimation You may have seen my previous post about estimating with markers. These are my candy cane estimation jars for Christmas. As you can see, I use 4 jars. Three jars show the children how different amounts of candy canes look in the jars, and “teaches” them to make a better guess. The last jar has a question mark on it, and this is the estimation jar.

Suzie's Home Education Ideas: Printable Place Value Slider On previous blog posts, I have shared some ideas on learning about numbers and place value as well as sharing my printable place value game to show some different ways we have used to learn about two and three digit numbers. I have since adapted one of my earlier resources, the Place Value Slider, to include four digit numbers. I originally got the idea of making a place value slider from here and made a three digit place value slider (pictured below).

Fractions by The Math Learning Center How To Use Fractions Working with Fraction Bars and Circles More Toolbar Items Overview Fractions lets students use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100. My Favorite Apps: The Number Rack and Math Slide If you have ever read one of my blog posts, you know how much I love bead sticks, bead strings, rekenreks and number racks. It will come as no surprise to you that I love the Number Rack App which is currently available for free through the Math Learning Center. The VERY best part is that it is an app for the iPad as well as being an app you can use through any PC and it also gets a lot of use on the SMART board!!!! Like other rekenreks or number racks, it allows you to work on big ideas around numeracy, addition and subtraction. You can go from one bead string up to 10 which makes it very versatile as I move between grades and ability levels.

Using Dot Cards to Build Number Sense - Math Coach's Corner “…that ability to ‘just see it’ without counting is called subitizing.” (Van de Walle)There’s no doubt about it…subitizing is all the rage! It’s not a new concept, though. According to Wikipedia the phrase was first used in 1949. Relentlessly Fun, Deceptively Educational: Climbing a Mountain of Addition [game] Games. Games. Games. I have figured out that I can get my son to do practically anything if I turn it into a game. This makes me feel like the queen of deception ... in a good way. To practice adding two-digit numbers (i.e. carrying numbers), I gave my son a mountain-climbing addition challenge.

Number Frames Overview Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities.
