I love teaching maths to firstgraders, you have many manipulatives, foldables, games... You can find tons of ideas on the internet. When teaching maths I find it very easy translating online printable resources but what I can't do is translating online games.
So here I am sharing some online maths games that my students play in Spanish. They are classified 1-6 grade. You can use it on your Smart Board or just send them to practice at home. Have fun!
