Number Corner by Grade

Number Corner outlines a coherent progression of skills development across grades K-5.

Kindergarten

Overview

Kindergartners add a new marker to the Calendar Grid for each day of the month. Students delve into important mathematics as they identify patterns that emerge in the markers over time. Each month also features a collection of some kind—cubes, sticks, shapes, coins, or data—that serves as a springboard for representing and analyzing data, practicing counting and computation, and solving problems. Students keep track of the number of days they have been in school, which gives them the chance to explore teen numbers and then all numbers to 100 and beyond.

Many days also feature an activity or game for strengthening students’ counting skills and computational fluency. These games and activities often incorporate visual models like five-frames, ten-frames, finger patterns to 10, linking cubes, and the number line.

The activities and games in Number Corner Kindergarten give students ongoing practice with key skills and concepts, including:

• Counting
• Reading and writing numerals to 20
• Comparing sets and numbers
• Modeling and solving addition and subtraction problems
• Identifying, describing, and comparing shapes in the environment

Overview

First graders add a new marker to the Calendar Grid for each day of the month. Students delve into important mathematics as they identify patterns that emerge in the markers over time. Each month also features a collection of some kind— cubes, sticks, shapes, coins—that serves as a springboard for representing and analyzing data, practicing computation, and solving problems. Students keep track of the number of days they have been in school using a hundreds grid, which encourages them to see groups of 1, 5, and 10 in different numbers.

Many days also feature an activity or game for strengthening students’ counting skills and computational fluency. These games and activities often incorporate visual models like ten-frames, double ten-frames, number lines, and hundreds grids

Overview

Fourth graders add a new marker to the Calendar Grid for each day of the month. Students delve into important mathematics as they identify patterns that emerge in the markers over time. Each month also features a collection of data that students gather by taking repeated measurements, conducting surveys, and performing experiments. The patterns on the Calendar Grid and the growing collection of data provide starting points for discussions, problem solving, and short written exercises.

Every month, fourth graders have multiple opportunities to develop their problem-solving skills while tackling challenging story problems. Students also have regular opportunities to play games and do exercises, often related to an open number line, that develop their facility with single- and multi-digit computation, fractions, equations, place value, or order of operations. A few days each month, students solve a problem string (a carefully arranged sequence of related problems designed to elicit specific computation strategies and insights about number relationships).

The activities and games in Grade 4 Number Corner give students ongoing practice with key skills and concepts, including:
