You are watching: What is a hidden question in math
Multi-step problems may require students to fix a covert question before they deserve to solve the initial question.
Solve multistep word difficulties posed with entirety numbers and also having whole-number answers utilizing the 4 operations, including difficulties in which remainders should be interpreted. Represent these troubles using equations v a letter standing for the unknown quantity. Evaluate the reasonableness of answers using mental computation and estimation strategies consisting of rounding.
In today"s lesson, the students learn to prize a multi-step problem by finding the answer to hidden questions. This set with4.OA.A3because the students fix multistep word troubles posed with whole numbers and having whole-number answers utilizing the 4 operations. I discover that student really have a hard time resolving multi-step native problems, thus, this is a an extremely necessary ability to be taught.
To gain started, i ask the students a question. "What walk multi-step mean?" i let the students think around the question. "Share her answer through your neighbor." By act this it allows students to share their way of thinking, and it may assist some student who execute not know just how to come up with the answer. Ns take a few student responses. Several students responded the multi-step means more than one step. Ns was pleased with the responses since this is no our first time hearing around "multi-step" problems. Periodically, us come throughout problems that require much more than one step in our "board work." The distinction with this lesson is that we deal with what the students space actually law to settle the multi-step problems. Ns tell the students, "Today, us will discover to uncover the hidden questions and answer them, in order come answer the original question gift asked."
I speak to the students come the carpet to talk about the lesson. The Multiple step Problemspower pointis currently on the Smartboard. Mine students are encouraged to speak out and answer or questioning questions throughout the whole course discussion.
First, I start by modeling exactly how to fix a multi-step problem hidden questions.
15 of mine friends checked out the movies critical week and also paid $8.00 each. 10 of mine friends visited the movie this week and also paid $8.00 each. How much walk they pay in all?
I describe to the students that in stimulate to find the total, i must first identify the surprise questions in this problem. The difficulty is questioning me for a complete amount that my friends payment at the movies. Prior to I can uncover the total, i must discover the amount the friends spent last week and this week.
The concealed questions:
How much money did my 15 friends invest last week?
How lot money did my 10 friends invest this week?
15 x 8 = $120
10 x 8 = $80
Now, we can answer the initial question of just how much go they pay in all. We require to add $120 to add $80 to acquire a total of $200.
I prefer to version for mine students in stimulate to display them what mastery that the ability looks like.
Next, the students aid me resolve the next problem.
My mommy bakes cupcakes for a bridal shower. She has 2 crate of cupcakes the she will deliver. She has 1 box of cupcakes that has 3 rows with 5 in every row. She has actually a second box the cupcakes that has actually 6 rows with 4 in each row. How many cupcakes walk my mom bake?
What are the covert questions? I allow the students to talk v their neighbors to number out the surprise questions. This confirmed to be daunting for the students. As they discussed, i probed castle with inquiries to aid lead them come the surprise questions. "What space they asking you come find? What calculations must you make prior to you can find the total number of cupcakes?" These varieties of concerns made the college student think. The college student knew to main point the number of rows through the variety of cupcakes in the rows, yet they can not affix this to a question that they to be answering. We had to refer back to the trouble that i modeled because that them. I put it ago on the Smartboard to have it in your sights together they thought about their questions. Finally, they were able come come increase with covert questions the they would have to answer.
The hidden questions are:
How many cupcakes were in the first box?
How countless cupcakes were in the second box?
I ask the students about the operation for the problem. I ask if there are any clue words come let them understand which procedure to use. The college student knew come multiply, then include the products.

3 x 5 = 15
6 x 4 = 24
Now, us can add 15 + 24 = 39. There room 39 cupcakes.
"From these examples, you can see that occasionally you need to find hidden inquiries in order come answer the initial question being asked that you. Friend will exercise this skill more in groups with her classmates."
