Original Prompt

use objects and pictorial models to solve word problems involving joining, separating, and comparing sets within 20 and unknowns as any one of the terms in the problem such as 2 + 4 = [ ]; 3 + [ ] = 7; and 5 = [ ] - 3

This resource focuses on teaching students how to solve joining problems using objects or drawings. It includes examples and practice problems that guide students in understanding how to add sets together to find totals. Initially, students are introduced to joining sets with simple problems such as counting blocks. They then progress to solving real-world scenarios involving apples and birds while learning the concept of adding quantities together. The document also covers separating problems, where students learn to find starting quantities by adding what was given away to what remains. Additionally, students practice comparing sets to determine differences, further reinforcing their understanding of addition and subtraction through practical exercises.
