Apparently, the Islamic State is doing everything in their power to teach their children math, while also using propaganda to brainwash their youth. It is said that as many as two million children throughout Syria and Iraq are attending these “schools” where they are brainwashed into terrorist thinking.

Children in the area are indoctrinated into the terrorist organization in order to become “pure soldiers.” That’s why they’ve been dubbed the “Cubs of the Caliphate.”

Recently, photos of a first grade textbook featuring guns, tanks and ammo have surfaced. The textbook, called “English For The Islamic State Book One,” was found in an elementary school in Mosul, the “capital” of the Islamic State.

The Telegraph explains how the photos submerged:

Raqqa is Being Slaughtered Silently, a Syrian opposition group of journalists against Isis, have posted similar textbook images.

The math book includes images of guns, ammo, tankers and ISIS flags in conjunction with different types of fruits, vegetables and animals.

According to Nikita Malik of Quilliam, a counter-extremism think tank, the Islamic State indoctrinates children in “a three-stage process.”

“First they normalize violence, then they expose them to things like executions and beheadings, and then get them to do physical training,” Malik told Top Yaps.
