Dinosaur Math By: Christy Gibson Kirbyville Elementary Second Grade
Dino Math • The game I created, presents the student with a math problem. • They have to solve it and type the answer in. • Once they have submitted their answer, they will receive a message that lets them know if they are correct or not. • The game is set to continue pulling random numbers for them to add together until they decide to quit the game.
But First… • However, before the students are released to apply their knowledge to this game, they will have to learn a few concepts. • Many of them at this stage still use manipulatives or their fingers to add. • They are not given this option when playing this game. • Therefore, they must first learn what we call “Mental Math.” • One of those concepts is“Making 10 to add 8.”
Making 10 to add 8: • In math, we often learn mental tricks to help when learning new concepts. • We are using manipulatives to help introduce the mental concept of “making 10 to add 8” to solve our addition problem today. • We will move the counters to represent the problem. • We first “make 10 to add 8”. • This way we set up our counters and then move 2 from the second number up to the first to make 10.
Let’s put it to the test!! • We need counters. • Now we need a math problem. • Let’s try 8+6= • What do we get when we add 8 and 6?
8+6=? • We start with eight red counters. • We set out six yellow. 1 5 1 5 2 6 6 2 3 7 3 4 8 4
8+6=? • Then we move the two counters over to the eight. • We have now made 10. • Now we should be able to add our 10 to our leftover counters. • We have 4 counters left over. • What does 10 plus 4 equal? • 10+4=14 • If this is the case, what does our original problem, equal? 1 5 1 2 6 2 7 3 3 8 4 4 10 9
Now Let’s try this method on our own: • Use your counters to try adding the following equations. • Group 1 - 8+9=? • Group 2 - 8+3=? • Group 3 - 8+5=? • Group 4 - 8+7=? • Group 5 - 8+2=? • Group 6 - 8+4=?
For extra practice: • Students can play this game to practice their addition skills and mental math techniques when they are ready to tackle the concepts without counters. • This can be used for the advanced students who already understand the concept, while you work with the ones that do not.
