Curated OER
Battle Shapes
Fifth graders play Battleshapes which is a variation of Battleship with geometry. In this geometry lesson, 5th graders get a graph paper with four quadrants. They call out coordinate points and attempt to sink their opponents shapes.
Curated OER
Sudoku
Young scholars work on sudoku puzzles. In this algebra lesson, students complete a puzzle by finding the missing numbers in a square. They use logic to solve these puzzles.
