We continued to work on subtraction strategies, this week. The first graders performed very well with the strategy of:

**Circling the numbers in the story****Listening to see if the story is subtraction or addition****Writing the secret code that matches the story (T-P=P or P+P=T)****Adding the number to the equation****Drawing the math mountain****Putting the total at the top****Clapping and counting ON or UP to solve for the missing number**

We are in the habit of checking to see if the number we solved for makes sense in the math mountain (the largest number always has to go at the top). If they make a mistake, the math mountain helps them to realize this.
