Here is a quick freebie called Eggs-Act Sums.
This is a favourite in my class - I think it's the novelty of using egg cartons! It's very easy to play and takes hardly any time to set-up.
Basically students roll two dice, find the total and add one of their counters to the space with that number. It's impossible to roll a 1 with two dice, so the first space has a star. This is a free space, so the second time a student rolls a number they can add a counter to this space since the other one will already have their counter in it. The first player to have 1 counter in every space wins.

Here is a quick one I did up in about 1 min using an egg carton I had a home.
I hope you can use it! Also my freebie will soon be available on First Grade Fanatics as part of their 14 Days of Summer giveaway. Here's a sneak peek:
