A foundational math lesson for kindergarteners to understand how teen numbers are composed of a group of ten and additional ones. Students will use ten frames and base ten blocks to 'build' numbers 11-19.

Students explore and practice multiple ways to represent numbers from 5 to 20, using visual models, symbolic notation, and linguistic forms to build deep number sense.

A lesson focused on developing one-to-one correspondence and cardinality by counting objects in circular configurations, specifically targeting the challenging 'teen' numbers 10-20.

A series of visually-rich activities for kindergarten students to master counting to 25 using touch-point numbers and sequencing exercises, specifically designed with visual supports for deaf learners.

A hands-on lesson focused on place value foundations, specifically the concept of composing a ten by trading 10 individual ones for 1 ten-rod using Unifix cubes.

Students practice adding two-digit numbers to one-digit numbers and multiples of ten, covering both regrouping and non-regrouping scenarios.

Students will practice counting groups of objects and writing the corresponding numeral from 0 to 20 in a nature-themed assessment.

A focused assessment on skip counting by 2s within the range of 2-10. Students identify the missing number in a single sequence to demonstrate mastery of the pattern.

A primary math lesson focused on using a hundreds chart to solve two-digit addition problems, including those requiring regrouping by composing a ten. Students will learn to navigate the chart by jumping tens (moving down) and ones (moving right).

A 30-minute lesson teaching students how to use a 100's chart to add two-digit numbers, focusing on 2-digit + 1-digit with regrouping and 2-digit + multiples of 10. Students will learn the 'Jump and Slide' method for navigating the chart.

Vocabulary assessment for Unit 2 covering time, counting, and problem-solving strategies.
