Number Corner is an essential part of the Bridges math program used by PNA from preschool through 5th grade. While a large part of number corner revolves around the classroom calendar, it is so much more than just finding today’s date. Using a spiraling theory, number corner provides daily practice in many broader mathematical concepts. Each day features short workouts to introduce and reinforce skills and concepts important to each grade. Number corner is full of critical thinking – thoughtful discussions, inquiries and problem solving – giving students one more opportunity to practice these skills and further their math knowledge.
Calendar Grid (K-5)
Each month has a different theme and pattern. Students are always excited to see the card flip on the calendar and confirm that they were able to continue the pattern. Sometimes the pattern is a color, shape, number, or image, and there are multiple patterns for students to discover.
Calendar Collector K-5
Each month students are collecting different “objects” each day. These collections promote deeper understanding in the skills of estimation, counting, place value, data and measurement. Kindergarten is collecting Unifix cubes in this month’s calendar collector. Each day, a student spins to see how many cubes will be added to the collection. The cubes are counted out on 5 and 10 frame mats to help students learn to subitize numbers. At the end of the month, the students use 10 frame mats to count out the cubes to find the total amount collected.
Second graders are collecting minutes this month. They collect 60 minutes each day that they are in school. This provides a good review of telling time to the hour on both analog and digital clocks, as well as learning more about the time cycles of a.m and p.m. It also reinforces the idea that the analog clock is divided into 12 increments of 5, helping reinforce the sometimes tricky concept of telling time to the minute.
Computational Fluency K-5
Different activities and games provide a hands – on movement based approach to developing fluency in math facts. Practice pages offer another way of practicing computation in addition, subtraction, multiplication and division.
Number Line K-3
The number line is used to assist students in sequencing numbers and counting forward and backward, as well as skip counting and developing strong number sense. In Kindergarten, Hap, the happy grasshopper, is used to engage the students in hopping while counting. First grade has Tad, the frog to help them and second grade has Cangaroo, a joey who hops along the number line.
Days in School (K-1)
In Kindergarten, students keep track of days in school by using linking chains to represent each day. The linking chains consist of five red links and five blue links to help students learn the skill of skip counting by 5’s.
In first grade, a volunteer adds a magnet to the grid. Right now, students have completed a ten frame and are working on filling in a double ten frame. Eventually they will reach a hundred and beyond! After adding the magnet, the class helps count the magnets and records the number of days they’ve been in school in number and word form. They also state how many ones, tens and hundreds the number has. Students then help come up with addition and subtraction equations for the number. Each part of this helps students see different ways to represent numbers. First graders also enjoy writing the month, day, and year in the number corner. They work as a team to help a volunteer remember and write the date in number and word form.
Daily Rectangle (2)
By building arrays to represent the date, second grade students discover that the same number can have multiple arrays. They record different equations to represent the sum as a total of equal addends. These activities prepare for fluency in in multiplication with repeated addition and skip counting as well as a knowledge in area and perimeter.
