Taking from Ten within 100 Practice
We know how to break numbers apart by tens and ones:
Try breaking apart bigger numbers by making a 10
We can use the Take from 10 strategy to solve subtraction problems
Let’s see:
Try it out!
Ben had 36 pencils, then he gave 4 to his sister. How many does Ben have left?
Activity #1
Directions: Fill in the missing numbers according to the pattern
Directions: Place the following numbers on the number line:
63 23 71 45 88
Directions: Make a number bond for each number with a 10
Activity #2
Directions: Build your number with base ten blocks. Then hide some! Your partner needs to figure out how many you hid. Then write an equation to represent your problem.
______________ - ________________ = ______________
Taking from Ten within 100 Game
a. Materials Needed: Paper, pencil, 2 dice per group
b. Students will play this game in partners. Each person starts with 100 points. One student rolls the two dice, and builds a two-digit number from the dice. For instance, if a student rolled a 3 and 6, they could create 36 or 63.
c. The student then subtracts their two-digit number from 100. Students keep taking turns until one person reaches 0.
d. Whoever reaches 0 first, wins the game!
