We have been rounding, expanding, rolling dice, reading and writing BIG numbers with Zero the Hero.
In this game the children grabbed 1 of 7 place value dice , rolled it , told the class their place value , how many digits in their room and then read their number aloud for me to record it. We then added these rolls to get a HUGE number for someone to read and tell me where the commas were to go.
It was fun and they are learning how to read large numbers and expand their own rolls with a 6 sided dice.
They played two games while completing their worksheets. In each case they were asked to roll one dice 1 digit at a time and decide where to put their roll to make the largest number. Stayed tune for homework rolling a smallest number to expand!
We played a trading ( regrouping) game to review the concept of regrouping. We began trading in 3 Town with the mayor as the trader. Everything in 3 town came in threes and the mayor would only trade if the student got three of any one color.
Basically, a player rolls the dice and asks the mayor for that number of YELLOW ( ones) chips to place on their board. Every time they roll, they must start with YELLOW chips. When a player gets 3 yellow chips they can trade in for 1 blue ( tens). When they get 3 blue, they can trade for 1 green ( hundreds) , and then 3 green for 1 red. You are the winner if you get to red first. We then repeated this game trading on 5 getting to red to win.
We then began using a place value chart with a 10 frame to trade and learned the word 'regroup'.
This game prepared us for regrouping and carrying over in multi digit addition and subtraction and was a nice review after our summer break.
Before the 5th graders went off to camp we began a review of Place Value as we prepare for the many math concepts that build on this understanding. Math skills and concepts like : basic number sense, adding and subtracting with regrouping, rounding & estimating, skip counting and multiplication, division, fractions and more. Understanding place value spans many grade levels and mathematical concepts. We have also been working weekly with our 100 boards.
Once the 5th graders return we will build on this concept across the grade levels and concepts.
We began by building numbers with physical blocks first then moved to a free app called Number Pieces which will be used later for more complex multi step math work.
Once the children can build a simple 2 digit number they were asked to build different 3 digit numbers!
Reading and writing large numbers in standard, word and expanded notation using a fun dice game and Popplet. Soon to be a movie as they explain how to round their number. This lesson was easy to differentiate and provide more practice. Rounding continues to be challenging for some due to its' multi step algorithm but playing games makes the needed repetition fun and engaging.
The children completed this worksheet in small groups and then made their popplets which will later be used in a simple movie to explain how to round their numbers.
We listened, sang and clapped our weekly math song, We Will Round You all week. We practiced rounding and ended this week rounding while racing our melting Zombie , eating green zombie skittles and walking like zombies. ( It is October ..)
We then made our own video of the song for others to learn how to round. The children hummed this song all. day. long. Music just sticks in our heads one boy said.
We played several games with cards or dice to create the biggest or smallest number value using the place value chart and expanded notation. In each game the children tried to beat the teacher's roll or card strategy. Children had to decide where to place their numbers to beat the teacher. Answers were then recorded, read and shared. Fun day! I lost numerous times!
Several games and variations of this bean bag game was played. In each variation there were recorders who kept track of the number tossed by writing it , reading it and adding the numbers to get a team's total.
The children have been reading and singing two songs regarding zeros and place value. One of the many activities done this week was to make a haunted house with 100s, 10s and 1s . Then they were asked to calculate their house value and then decorate their scene.
The following day they scooted around the room with clip boards figuring out each other's value and then calculating the class' total value.
Fun! I played Halloween music to set the mood . BOO!
