Join me as I ‘dive’ into using these centers.
After downloading the 25 page file, you will have some cutting to do. I cut all of the game pieces and placed them into sandwich or snack sized Ziploc baggies. I then grabbed a gallon-sized Ziploc baggie. I placed the title page inside along with the smaller baggies and they were ready to go. At school I have one larger tub with hanging files inside to sort my math games. These should fit great into those hanging files.
Here are the four math centers along with the cover page, common core objectives (2nd grade), and table of contents.
Math Center #1 – Ocean Animal Skip Counting Puzzles
These puzzles allow students to practice skip counting by 5s, 10s, and 100s. They will keep your second graders entertained with their bright and colorful creatures. I was thinking that students could try to beat the clock or have a friendly competition to see who can complete their puzzle first. This center does not come with a recording sheet, but it would be simple for second graders to record the number patterns on a piece of paper, especially if you need an accountability piece.
