Factoring Trinomials Enquiry Stack - Updated Alongside Gcfs!

I wasn't quite certain what to spider web log virtually today, together with thence I started looking through my drafts folder inwards Blogger.  I ran across this post service on a enquiry stack I created for factoring trinomials during Algebra 1's unit of measurement on polynomials.  

I commencement blogged virtually this activity inwards Nov of 2015.  Here's the link to my master post.  

I generally kept the same questions, but I edited unopen to of the problems to brand my students conduct keep to element out the GCF first.  

Here are the questions: 

Here are the answers; 

I intentionally added 2 questions amongst a GCF of 2 together with 2 questions amongst a GCF of x^2.  This meant that students wouldn't hold upwards able to automatically figure out the right respond merely past times identifying the GCF.  

So, how does a enquiry stack work? 

Students are given a double-sided deck of 10 cards.  One side of the carte features a question.  The other side features the respond to a DIFFERENT enquiry  Many people mistakenly assume that the respond printed on the dorsum is the respond to the enquiry on the front.  These may hold back similar flash cards, but they are definitely non flash cards.    

Students get the activity past times turning over all of the cards to let out ALL of the answers.  I say my students this is their respond bank.  

Then, students flip over i carte of their choosing.  This volition hold upwards their commencement occupation to solve.  When students notice the solution, it should hold upwards inwards the respond banking concern if they conduct keep done everything correctly.  They selection upwards the solution carte together with flip it over to let out the adjacent question. 

I dearest enquiry stacks because they are self-checking.  This agency I tin laissez passer on the sack focus my assistance on the groups struggling the most.  The respond banking concern gets smaller together with smaller amongst each enquiry which helps gear upwards pupil confidence.  

Here are unopen to pictures of my students inwards activity piece doing this activity: 

Want to larn to a greater extent than virtually the box method for factoring polynomials?  I propose that you lot read these 2 posts: Post 1 together with Post 2.
