Our Add Within 100 lesson plan teaches students strategies for adding two numbers less than 100. During this lesson, students are asked to practice solving problems in which they add one and two digit numbers. Students are also asked to play a game in which they roll a dice and add that to a two digit number for additional practice.
At the end of the lesson, students will be able to add within 100 with two-digit and one- digit numbers including multiples of 10 using a strategy based on place value.
