## Start unknown word problem

Teachers who have purchased my word problem materials for Kindergarten, 1st grade, and 2nd grade send me about 4 to 5 emails a week. The majority of the questions I get are from students who are having trouble learning what to do in addition and subtraction situations.
I am not a math guy, as I have said several times before. In reality, I was one of those students who despised it due to math phobia. I, on the other hand, have done my “homework” in terms of not allowing my students (and my own boys) to get to that point, and I’d like to share some insights with you today.
There are only around 14 to 15 different forms of word problems. Others are more complex than others, but by the end of second grade, when the children have been introduced to all of them, they should be able to solve these addition and subtraction problems with ease.
I can tell you from experience that unknown start and unknown change issues are often more difficult than the others. This is due to the fact that when my students are getting ready to model the issue, they have no idea where to begin… because the beginning is unknown!

I begin by asking students to assist me in creating a visual representation of the issue.

I have a volunteer draw a photo of seashells at the beach on the monitor. Since drawing 65 seashells is boring, I give students white boards and instruct them to solve the problem using the picture as a guide. As students practice, circulate to see what techniques they are using and what common errors they are making. New Material is Introduced Time limit: 10 minutes I’d like three students to explain how they approached this issue. I’ll draw and document your solution on this map as you speak so that everyone can see how you solved the issue.
These various solutions can be written down or drawn on open number lines, and they should be addressed in class as feasible and distinct approaches to solving the problem.

You’ll now have the opportunity to collaborate with a partner to solve one of these problems. To solve this problem correctly, use the methods we’ve discussed. You can draw an image of the dilemma, just like we did as a group, to figure out what the best number sentence is.
