Step 5: You can play it by yourself too!
If you want to practice your math facts to build your math sense but no one will play with you, here's the way to do it.
Deal just 4 cards, face up. These are the cards you use to build your equation. Flip over the top card on the deck. This is your "answer card". When you find the solution, remove only the cards you use for the equation including the answer card. Turn over new cards until you have 4 cards on the table again. Flip the next card for the answer and start again. You "win" the game when you remove every card from the deck and the table with your final equation.
When teaching the solitaire game to my students, I show them the way to play and guide them through a few rounds. Once I think they have the idea, I turn the 4 cards for the equation but do not turn an answer card. Then, we check their understanding by asking if they can find a way to make each digit (1-10) from the 4 cards in play. Here's what that looks like:
If the equation cards are 1, 4, 5 and 7 what can you make? Remember, you must use at least 2 cards for each equation. The results:
We made it! It is not always that easy.
Try this set yourself:
4, 6, 7, 10
I don't know about you but finding an equation for 6 was tough.
One more for you:
8, 8, 9, 10
I can't figure out how to make a 4 or a 5, but the rest of them are there.
