Africa: Infinity Street

Infinity Street: A Place Value Activity


Dive into the world of units, tens, hundreds, thousands, and millions with Infinity Street, a Montessori-inspired place value activity where each house represents a unique number family. As children work with Infinity Street, they develop a deeper understanding of numeration and place value.

Designed for both home educators and elementary teachers, this comprehensive package covers several essential math skills while exploring country populations throughout Africa.

  • 3 Infinity Street houses, representing the simple family, the thousands family, and the millions family
  • 24 task cards divided into 5 sets, each focusing on a specific math concept
  • 16 African country population cards, with both color-coded and a non-color-coded options available
  • 2 Infinity Street place value mats
  • 2 Sums & Differences place value mats

Print the Infinity Street activities on cardstock. Cut out the Infinity Street houses and mailboxes, along with the task cards and country population cards. Laminate the materials for durability.

Both the country population cards and task cards may be stored on a ring binder clip for easy organization. Once the place value mats are laminated, students are able to write on them using a dry-erase marker or Stabilo crayon.

Infinity Street is a Montessori-inspired place value activity. Along Infinity Street are houses that represent each number family, starting with the simple house, followed by the thousand house, the million house, the billion house, etc. Within each house live the units, the tens, and the hundreds.

As children work with Infinity Street by building the country populations and completing the included task cards, they will develop a deeper understanding of numeration and place value.
