This simple math quiz is suitable for grades 4 & 5 or any pre-geometry students. Students will read a geometry term and match it to its correct definition.Terms included in this quiz:* congruent* right angle* obtuse angle* acute angle* equilateral triangle* scalene triangle* isosceles triangle
$1.50 Triangles (Foldable) This foldable includes six tabs, classifying triangles as follows: -Acute -Right -Obtuse -Equilateral -Isosceles -Scalene I have students write the definition on the tab and mark each of the triangles using appropriate slashes, arcs, and right angle indicators.
This fun and differentiated sorting activity helps students understand the difference between acute, right, obtuse, equilateral, scalene and isosceles triangles.Included in this activity are:-Headings for acute, right, obtuse, equilateral, scalene, and isosceles-Also includes 9 headings for combination triangles (acute scalene, obtuse isosceles, etc).-Definition cards for all headings-24 sorting cards -Answer key-Teaching tips-Student recording sheet.
