Number Bonds = Better Understanding [Rescued from my old blog.] A number bond is a mental picture of the relationship between a number and the parts that combine to make it. The concept of number bonds is very basic, an important foundation for understanding how numbers work. Number bonds let children see the inverse relationship between addition and subtraction. A Picture Is Worth More than Many Words You can draw number bonds on paper using circles or bar diagrams. Math textbooks often try to communicate the same concept using four-fact families. The idea of the four-fact family is to help students realize that once they know one of the facts in the family, they know all of them. How to Teach Number Bonds When you start teaching number bonds, use M&Ms or popsicle sticks or whatever you have on hand to make physical piles that can be pulled apart and pushed back together, then pulled apart in another way. “How many blocks do we have here?” Kitten counted carefully. “1, 2, 3, 4, 5, 6.” She did not have to count those.

Debbie Diller I wish I knew the best way to explain my Math Stations. I've said it many times, I like it simple, clear and meaningful. So ... in a nutshell... here is how I run my math stations in my 2nd grade class. Each month I cover 12 CC standards. 4 from each domain: Base Ten Notation Fluency w/ Addition and Subtraction Measurement Geometry/Data This can be found on page 1 of my centers... below is March. Storing the completed set. The first year, I had the expense and lamination to cut... however, since then... it's been easy!! I use these fancy storage boxes (he! Each month has its own box. The bottom picture (of the post) shows what the inside of the fancy box looks like. 12 large baggies of math station task card, talk card, activity, manipulatives etc. I took pictures today of our last rotation in March. I have 12 pairs of kids working around the room... completing their activity in the box, completing their workbook and then playing a math facts game board until the timer goes off. page 2... box 2

That's So Second Grade!: Daily 5 Math & a FREEBIE! After jumping head first into Daily 5 for my literacy time at the start of school, I decided I would take the plunge with math as well. Using Daily 5 for my reading and writing time has had it's kinks, but has been the very best thing I could have done to create a classroom culture grounded in literacy and reading. Until I starting using the Daily 5 structure for my math time about two weeks, my math block went a little like this...I would teach a WHOLE GROUP LESSON or activity for about 20-25 minutes. Then students would all complete the same worksheet or activity at the same time and when they were finished they would go to either me or my assistant and have their work checked. I had previously heard a little about Daily 5 Math from reading on the Sisters' Daily Cafe website, as well as on a few blogs here and there. There is no book about Daily 5 math (yet -- but I hope there will be one soon) and there is not much out there resource-wise for how this looks.

5 au quotidien en math Réflexions en cours... Je n'ai pas encore implanté les 5 au quotidien et la méthode CAFÉ que je rêve déjà de l'implanter pour les mathématiques. En lisant à droite et à gauche, j'ai lu à quelques endroits les 5 "ateliers" de base en mathématique selon les auteurs des 5 au quotidien. Je ne suis pas certaine que cela corresponde à ce que j'ai besoin. 1. Jeu de nombre2. En continuant mes recherches, je suis tombé sur un concept bien sympathique qu'est le B.U.I.L.D B pour Buddy Games (Jeux entre amis)U pour Using manipulatives (utiliser le matériel de manipulation)I pour Independant reading/work (lire des livres de mathématique)L pour Learning about numbers (apprendre les nombres)D pour Doing math (faire des maths) Mais, encore une fois, je ne suis pasconvaincue que c'est vraiment ces composantes que j'ai envie de mettre en place dans ma classe.
