This number line is an effective way to present numbers and operations in base ten. It is a tool that helps to show modeling and can be kept up all year. The number is written as a word, shown as a number and modeled using base ten blocks.

In this PDF document you have two different visuals. One poster shows the steps to adding two digit numbers, the other poster shows the way to use a hundred chart to add or subtract multiples of ten from a two digit number. There are plenty of review sheet from basic drills to problem solving applications. If you would like contact me and I can provide you with a much larger poster if you want it on display at no extra cost.

This PDF should be printed on card stock, or laminated. Estimate printing about 1 to 2 pages per student. In my class we call this game 'War', but call it it whatever you want! Basically it is played in pairs, where each kid has about 10 cards that are face down. On the count of three both players flip over a card, the first one to add both cards' numbers gets to keep both cards, the player with all the cards at the end wins. As they become more advanced I change the rules and they they have to

Each day I have my students do a math choice board. Each child will get to pick 2 of 4 possible math problems. I indicate harder problems using a star, easier ones with a happy face. In order to help make sense of what each child gives me I have developed this generic handout. On it there is space for in depth thinking to be displayed, a math sentence and the answer.

In presenting addition using common core, children are expected to visualize number patterns, without necessarily having to count them. The patterns up to the number six should follow those of a die, however past 6, a ten frame is necessary. This PDF document contains the visual patterns from 1 to 6 on a safari themed background.

This activity can be given to the above level kids that finish early. After teaching that addends produce a sum, you can have kids use the sum to find addends. The workmat is included for those tactile learners.

This PDF can be used on the smartboard (or any projector) as tool to reinforce common core's emphasis on familiarity with spatial patterns. I set a goal, depending on your children's ability. Last year my goal was 60 in a minute, if the kids could reach that goal I gave them a pizza party. Once that goal was reached we decided on another goal (240 in 2 mins. ) Have fun with it, initially make sure that they point to the larger number and count on OUT LOUD for the smaller number. This is importan

I do daily problem solving with my first graders. It is all common core based. There are many children who can do basic computation but who struggle with word problems. I suggest having children read the problems aloud and allow time for discussion.
