SPEED! Variation 2 - includes finding averages

Another version of SPEED! that the boys can play on their own is what we call SPEED! Cross-Out.

For this game the player has to write the sequence of numbers he is working on. Here Douglas is working with the SEVEN SPEED! cards.  So he writes the numbers 7, 14, 21, 28, 35, 42, 49, 56, 63, 70 three times in columns on a sheet of paper. 

Then he shuffles the cards and flips one over at a time. Working with only one column at a time he crosses off the number turned. If the number has already been crossed off, he simply flips another card.

When a player has crossed off all the numbers, he counts how many cards he flipped and that is his score for that round.



After he has completed three rounds, he figures his average and that is his score for the game.

In this way, Douglas, age 8 and working on the SEVENS, and Charles, age 6 and working on the THREES, can compete. Douglas gets the extra practice of the skill of figuring averages.
