1. Assemble a domino puzzle
Print the free puzzles at the link below. Then grab some dominoes and start filling in the puzzle one piece at a time by placing a domino that adds up to the number shown in each rectangle. The trick is that regular domino rules still apply, so each number must touch another domino with the same number on that end.

2. Play tic-tac-toe with addition problems
Work out the answer to each problem in the grid, and dot or circle the ones that add up to 10. First to get three in a row wins!

3. Face off in Dice War
Dice games are fantastic in the classroom! With this one, kids practice their addition facts and get a little work with subitizing too. The concept is so simple: Each player rolls the dice and adds up their numbers. The highest sum wins that round. This is one of those first grade math games that can be expanded by adding a third die. (You can also use playing cards.)

4. Use sticky notes to make 10
Sticky notes have so many uses in the classroom. In this case, challenge students to put together the numbered notes that “make 10.” They’ll practice adding to 10 with multiple numbers. You can also do this with subtraction, starting at 10, to make zero.

5. Play Shut the Box
This game has been played for hundreds of years, but it’s a fun and sneaky way to practice addition facts fluency. The goal is to “close” each of the numbers in the box from one to nine by rolling the dice. For instance, if a player rolls 11, they may close 1, 2, 3, and 5, as these add up to 11. If no numbers are available to add up to the dice total, play passes to the next player and continues until someone finally “shuts the box” by closing the last available number. You can play this game with a specially designed box, as it has been played for years. You don’t need the box, though; simply have kids write out the numbers 1 through 9 and cross them out as they play.
6. Assemble some addition grab bags
Fill a variety of bags with collections of small objects. Kids grab a handful from two different bags, then count and add up the results. Be sure they write it all down to get practice at setting up equations. First grade math games like this one work for subtraction too.

7. Face Off to find the difference
Each player rolls the dice (try polyhedral dice for higher numbers, or roll several dice and add them together) and builds a stack of math cubes. Then they “face off” and find the difference between their two stacks.

Find out the answer and solution
Solution
1. A rabbit is lighter than a puppy, so the right one is lighter. the bowl with the rabbit will rise up.
2. In order for the balance to balance, the weight on the bowl rabbit should be 2 kg heavier than the kettlebell that we will add to the puppy.
It turns out that you need to put on a bowl with a puppy weight in 1 kg, and on a bowl with a rabbit - in 3 kg.
