### Urchin Math Focus Groups

#### Fun with Math Group 1

This group will focus on having fun as we use mathematical reasoning, perseverance, and critical thinking to work on real life math problems. Emphasis will be on having a Growth Mindset as students explore different ways to solve problems using a variety of skills, logic and critical thinking and to share their reasoning with each other. We will focus on the Math Practice Standards

11/6 and 11/13: Students learned about arrays to represent multiplication problems and students built their own arrays using cubes, i.e. 4 X 6 = 4 rows with 6 columns or 6 rows with 4 columns. They played "Race to 100" where they filled in X arrays and wrote the corresponding equations. Please keep practicing building X problems at home.10/23 & 10/30: Students played a dice game where they "built" multiplication and division problems and solved them using "Fact Families". For example, in the Family of 3, 4, 12, students built and multiplied 2 ways and divided in 2 ways (3X4; 4X3, 12 divided by 3; 12 divided by 4). They also recorded equations and took them home to practice. Next week: more X and related division practice.

10/16: Students learned more about the commutative property of multiplication by playing a game called Commutative Cookies. They partnered up, rolled a die for # of cookies, rolled a second die for # of chips, built the problem and wrote the multiplication equation to show the problem and answer. Because multiplication is commutative (the same forward and backward, they build the equation again showing the same numbers reversed and wrote the new equation. Next week we will play with multiplication and it's inverse: division.

10/9: Students learned about the Commutative Property of Multiplication (2X6 = 6X2). They built their X problems with a game about cookies and chips and they had fun playing this game in partners. They will continue this game on 10/16 with new combinations of multiplication, new partners and a recording sheet where they write the equations.

10/2: Today students brainstormed agreements about how they would like to be treated in math group (listened to, supported, focused, etc.). Students got to know each other by playing a "Value of Your Name" game where they figured out the monetary value of the letters in their first name and then compared the value to their friends. They used subtraction to find the difference between names, found the closest and farthest in values, and had fun extending the learning to other comparisons between friends.

#### Fun with Math Group 2

11/13: We played a multiplication dice game.

11/6: We learned about arrays to represent multiplication problems and students built their own arrays using cubes, i.e. 4 X 6 = 4 rows with 6 columns or 6 rows with 4 columns. They played "Race to 100" where they filled in X arrays and wrote the corresponding equations. Please keep practicing building X problems at home.10:23: After a brief review of last week's "commutative property" of multiplication some students chose to go on to division and played a dice game while others learned a math strategy game, Poker. Next week: Fact Families for multiplication and division.

10/30: More Multiplication and Division games using spinners to practice "fact families" i.e. 6,7,42.

10/16: Students learned more about the commutative property of multiplication by playing a game called Commutative Cookies. They partnered up, rolled a die for # of cookies, rolled a second die for # of chips, built the problem and wrote the multiplication equation to show the problem and answer. Because multiplication is commutative (the same forward and backward, they build the equation again showing the same numbers reversed and wrote the new equation. Next week we will play with multiplication and it's inverse: division.

10/2 and 10/9: Same as above.

**Groupers Math Focus Groups with Joy**

**Group 1, 9:35 - 10:35**

11/14: Students learned about about probability as they played a dice game with ratios of possible numbers combinations.

11/7: We had more fun with ratios and proportions and learned how to compare equivalent ratios. Students had an introduction on cross multiplying to find the value of an unknown number (n). They continued their game of X squares. Next week: Probability.

10/31: In honor of Halloween students measured bones in their bodies and formed ratios to compare formed ratios to compare (humerus compared to ulna; femur to tibia). They continued their multiplication squares game with partners.

10/24: Students watched a video explanation of ratios and rates that I recommend here. We used # of pets to #of family members each student has to compare, then we doubled both numbers and saw the equivalent ratios. We also worked with bigger numbers converting them to ratios and comparing them. At the end we played a multiplication squares game. More of the same next week!

10/30: Same as above, measuring bones of body and forming ratios. More practice with Poker.

10/24: Students watched a video explanation of ratios and rates that I recommend here. We used # of pets to #of family members each student has to compare, then we doubled both numbers and saw the equivalent ratios. We also worked with bigger numbers converting them to ratios and comparing them. At the end we learned how to play Poker (a good math strategy game.) More of the same next week!

10/17: After a review of Mean, Median, Mode and Range we again used the weather map to look at weather around the country, comparing highs and lows, tides and moon phases. Realizing we needed a geographical refresher we used the map to look at countries and continents in N. America and to learn about the world. At the end of class we learned a new strategy game called Rumikub. ** **

10/3: Students brainstormed and came up with** **some agreements about what they wanted from their math group. We watched a Growth Mindset video. Students figured out the "value of their name" by using a sheet where dollars corresponded to letters in their name, then compared the differences between their names and those of their friends. Then they wanted to multiply the letters in their name which got a bit crazy with one student having a name with 8 letters! The group had fun working together.

**Group 2, 11:10 - 12:10**

11/14: Students learned about probability as they played a dice game with ratios of possible numbers combinations.

11/7: We continued learning about ratios and proportions and did a task called" The Giant's Coat". Students used the proportions of their own thumb, wrist, neck and waist to determine equivalent ratios of the giant's proportions. We ended class with more fun with Poker. Next week: Probability.

10/17: After a review of Mean, Median, Mode and Range we again used the weather map to look at weather around the country, comparing highs and lows, tides and moon phases. Realizing we needed a geographical refresher we used the map to look at countries and continents in N. America and to learn about the world. At the end of class we learned a new strategy game called Rumikub.

10/3: Same as above except instead of finding the value of their names students tried to determine which fraction didn't fit using 1/2, 2/8, 1/3 and 3/4. The emphasis was on sharing their thinking and backing up their opinion with "evidence". Everyone had a different answer and everyone was able to back up their point (which was the purpose of the exercize)!

**Groups 1 and 2:** 10/10: We learned about mean, median and mode, range and used examples from student's lives. Then students used a weather map to practice the concepts with temperatures of a week's worth of weather which was retty interesting! At the end of class we played Uno just for fun!
