 Critical Thinking
Pros: Lessons include instruction, practice, and quizzes, and kids can go back and retake quizzes to improve their scores.
Cons: The learning coaches' voices are a little awkward, and lessons must be completed in order regardless of skill level.
Bottom Line: With its customizable reward system, extensive progress tracking program, and detailed lessons, this site is a valuable resource for teaching math.
GPALoveMath could be used in the classroom as an instructional tool to support any math lesson that connects with the included content. It takes a bit of time to get started, especially if you plan to customize the reward system beyond the default settings. Plan to spend at least a couple of days testing out the site's features and viewing the tutorial videos. Once kids are set up in the system, have them complete a placement assessment. This will generate customized learning paths with lessons that can be completed in sequential order. It could be fun to have kids use the Engage feature to share what they've learned with their classmates.
Continue reading Show lessGPALoveMath is a subscriptionbased teaching resource for kids from kindergarten through fifth grade. Kids start by taking a placement assessment, and then the program creates learning paths to match their skill levels. A comprehensive dashboard tracks kids' progress, and emails are sent to adults when kids complete lessons. There are so many features and tools that it can be overwhelming to get started, but there are video tutorials and builtin tips to help.
There are three main components to the learning pathways: Learn, Engage, and Motivate. In the Learn section, kids complete lessons that include instruction, practice problems, and 15question quizzes that are similar to the practice problems. Kids earn points for completing quizzes, and the points accumulate and can be used to redeem rewards. In the Engage section, kids can send a friend code to connect with friends and family, allowing them to share their accomplishments and experiences with others. This could be particularly fun in the classroom as a way to promote some friendly competition. But it's up to an adult to monitor conversations once kids have connected with friends. The Motivate section includes the rewards that kids can earn for their accomplishments. Adults organize and customize this section, with options for using systemgenerated rewards or creating original rewards from scratch.
The resource addresses numerous Common Core State Standards, although they're not all covered in great depth. There's some good content baked in: Kids can learn important math skills ranging from counting and basic addition to operations with fractions and decimals, and it's easy for kids and teachers alike to navigate the sections to hone in on a particular skill set. It's also nice that kids and their teachers can customize the site to get rewarded for different achievements, like high scores or persistence.
It would be great if that Engage feature could let students have an even more highimpact social experience; in addition to sharing their achievements, it would be great if kids could help each other or otherwise delve deeply together into the work at hand. It can also take a while to get things set up just how you want them for the classroom, and some kids and teachers might find the sheer volume of info here overwhelming. Overall, though, this tool is solid: GPALoveMath provides wellrounded learning opportunities for kids, and it's a handy teacher tool; it's definitely worth a look.

 5.NF.5.b
Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence a/b = (n×a)/(n×b) to the effect of multiplying a/b by 1.
 5.NF.6

 5.NF.7
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.1
 5.NF.7.a
Interpret division of a unit fraction by a nonzero whole number, and compute such quotients. For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3.
 5.NF.7.b
Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (1/5) = 20 because 20 × (1/5) = 4.
 5.NF.7.c
Solve real world problems involving division of unit fractions by nonzero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3cup servings are in 2 cups of raisins?

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.
