I have found that games are great to reinforce a concept. This place value and numbers game you play with a 100 chart and Uno cards are perfect to work on knowledge of two digit numbers plus place value- thus which number is the greatest!
Playing this game you need the printables(free!) which include a 100 chart and rules, 4 player cards and also player pieces corresponding to the color of the players. (Also see this simple 100 chart game younger children enjoy.)
How to Play:
The first player starts and picks up one card. The first card goes onto the first block, the Tens place(unless it is a zero, then it can only go onto the last/Ones block). The rest of the players have turns to pick up their first cards. Here the players will already start to compare numbers and guessing what their chances are for getting the highest number.
Then, players pick up their second card- for the Ones place, and say which number they have. They then take their play piece and place it on the correct number on the 100 chart to see who is the closest to 100- who has the greatest number. The greatest number wins the round.
It is easier for younger kids to see who wins when using the 100 chart. It also helps them to get used to using a 100 chart. Older kids might choose to not use the chart, which is perfectly fine.
The circles on the player cards are used to keep score of winnings. You can play until one player has all the circles ticked, or choose to play until one side is ticked by the forerunner.
A great game to play with children to teach two digit number recognition, number names and place value while having fun! When children grasps the concept of the game one can play with 3 or 4 cards- challenging 3 or 4 digit knowledge and without the chart or player cards, just a card game!
