1. Happy Numbers
Happy Numbers is a great website that allows students to practice math skills Grades k-2. All of the skills are Common Core Standard Based and have a visual representation and on-screen hands-on learning. You can put students in up to five groups and assign certain standards to each group. You can get a 30 day free trial and can load multiple classes under one username. If you choose to purchase, it is only $59.00 for the year! It is so engaging and very simple to check student progress and differentiate with!
This is a WONDERFUL free resource and something that you could use of skill practice besides just math! It is a game-based practice tool. The teacher can load their questions and answers in and the students can play as individuals or on teams. The best part...after the game is finished, you can get a spreadsheet report as a teacher, so you know exactly what each student got right/wrong and what they answered! The kids LOVE this website!
Both of these resources are web-based, meaning that you can use a mobile device, a tablet, an iPad or a computer!
